NBA 2K21 Next-Gen AI - A Deep Dive Into the Offensive and Defensive Improvements

The third (and final) next-gen gameplay blog just went live, and while there’s a ton in there, I wanted to focus on the NBA 2K21 next-gen AI improvements coming to offense and defense. It’s not that I don’t care about MyPlayer, badges and so on, but AI feels somewhat split off from those pieces of the blog. We may have a deep dive into those other elements in the near future as well, but in the meantime let’s chat about the AI.

How Happy Are We With AI Right Now On Current Gen?

I’m of the mind that the AI has seen better days. It’s not so much that it’s gotten worse this year (even though it has), it just feels like the AI has stagnated in some areas. Let me quickly run through some basic high-level stuff.

  • Five out is very popular in 2K, but there’s no real “easy” way to make your center roam (unless you user) if he has to guard some big who can’t shoot a lick. In other words, the defensive settings at your disposal don’t really allow you to focus in on playing 4 on 5 unless you off-ball. I know some people may claim otherwise, but even if it is possible, it’s not as straight forward as it could be to make this sort of thing a reality.
  • The AI chooses terrible double team strategies on defense far too often.
  • Charges have become more non-existent than they should be as barreling into the paint is a very common tactic and it can be hard to defend without off-balling as well.
  • It can be way too hard to tell your AI defenders not to leave corner shooters. Much like with not having a great way to tell an AI defender to leave the non-shooting big at all times, your team defense is always somewhat on a string and makes certain rotations even if you are trying to avoid them making those certain rotations.
  • General AI flaws like minimal turnovers, even from player types that should turn it over more, and excessive offensive rebounding from AI teams.
  • Transition defense is a hot mess.
  • I separate out things like AI recovery speed on defense being way too strong and loose ball shenanigans as not strictly “AI improvements on defense” but rather things the AI just needs to not be so good at.

There is a ton of room for improvement with AI, and some of that will hopefully come from ratings/badges/tendencies being more refined and mattering more. But now let’s get into the AI upgrades being touted.

NBA 2K21 Next-Gen Defensive AI Improvements

  • “New switching logic update: Both on-ball and off-ball screen logic has been rewritten and the auto-switching logic was refined to reduce bad switching instances. So expect to see fewer cases of the AI calling for a switch without a screen and leaving a player open.”

Let me first say, I hope there’s a better way to save individual defensive settings in online games so you don’t have to set these things every game online. The same goes for offensive playbook/settings. Whether it’s MyTeam, or MyLeague Online or Play Now Online, 2K needs to do better here. Otherwise, what’s the point of having all those options to set? It’s not reasonable to expect us to do these changes at the start of every game.

Okay, with that said, there’s a couple parts to this first improvement. Long-time veterans have probably given up on auto-switching many years ago and tend to tweak that so no switches happen unless they say so. The AI can’t be trusted, and there’s just never been a great rhyme or reason to the switching. Part of that is probably realistic as I imagine it plays into individual defensive awareness ratings, but the point is it’s really hard to trust the AI to switch at the right times.

With that in mind, will I now leave auto-switching on more often and trust the process? Sure, I’ll give it a chance. The most egregious switching tended to happen on pick and rolls and off-ball screens, so let’s get to those improvements next here.

  • “Improved logic for defenders in avoiding each other when moving around obstacles. This works hand-in-hand with the off-ball movement changes I detailed in last week’s blog.”

In short, this first ties into the concept of “suction” and how much it still will happen. 2K is claiming you won’t be sucked into screens as much, and that’s one part of why the avoidance will be better. This matters for AI defenders off ball, and it matters when playing on-ball defense. Again, I want to believe you won’t be sucked into screens as often, and that will in turn allow you to better control when you go under/over an on-ball screen.

  • “Overhauled the Hedge defensive system for better screen positioning and angle targeting.”

This one is slightly more confusing for me in terms of how it’s worded. If the hedge defensive system is overhauled, then why are we talking about screen positioning and angle targeting — those seem to imply what the screener is doing on offense. That being said, if this means AI defenders hedge on pick and rolls by taking better angles, then cool.

There are multiple reasons it’s “meta” to be the big/hedge defender rather than the on-ball defender in pick and roll scenarios, and one of them is the angle the hedge defender takes is too inconsistent and random. Whether you set the hedge defender to drop or hard hedge, there’s not always great consistency here and a relatively skilled player can pick apart these situations as the ball handler.

  • “Adaptive Coaching Engine (ACE) now has the ability to recognize and adapt to different types of off-ball actions including: Flare screens, Down screens, Back screens, and Handoffs.”

Okay, while I may trust “auto-switching” for a short period of time on next-gen, hasn’t ACE sort of burned so many bridges it can’t be trusted even with next-gen NBA 2K21? I feel like fans would be happy if there was just a way to make sure ACE stayed off if you set it to off rather than always fearing it’s somehow come back on and is ruining all your defense/offensive settings you went out of your way to set.

That being said, I would love to be proven wrong about ACE. I hope it does pick up on certain off-ball actions happening a lot and tweaks your defense to better handle it. It would be dope for those of us out there who don’t want to micromanage every little thing.

  • “Several improvements to transition defense.”

I’m not really sure what to say about this beyond simply saying “good.” There needs to be at least several improvements to transition defense because it’s rough. Players don’t get back after makes at times, they don’t match up, they don’t pick up their assignments beyond the 3-point line quick enough, and yet they also don’t pack the paint well enough either in other instances. Oh, and while it’s not defense related, nerfing outlet passing so not everyone can throw Lonzo Ball bombs would also help.

However, my top pet peeve and something that I pray is finally fixed after years and years is the transition buckets that occur after missed free throws. Without a shadow of a doubt, the easiest way to get a transition bucket in this game comes after a missed free throw. Please let the madness end.

  • “The player can now call for help defense by holding L1/LB instead of just calling for a double team. This is a great mechanic that you can use when guarding the ball; instead of hoping the AI selects the right time to send help, it’s now under your control with a simple press and hold of the button.”

2K loves to make these sorts of changes, and I’ll always support them trying these things out. Double teams have always largely been bad in the 2K series, so if they want to transition to something like this instead, then fair enough. This could be a band-aid of sorts for the idea of leaving someone in a five-out system, but you would need to easily be able to key in on who you want to be that help defender. I like this concept in theory.

  • “Improved logic for CPU defenders to get in position to take charges.”

Again, sounds great but would have loved to read a little more info. We also need to make sure charges themselves are easier to come by. Mike Wang did talk about contact in the paint in last week’s blog, so I imagine this improvement sort of ties into that tenet as well.

NBA 2K21 Next-Gen Offensive AI Improvements

  • “Next-Gen Game Planning: This is a great new feature that allows players and AI to have more specific game plans for their teams. In the past, you could choose to run pick & rolls with LeBron, but the new system allows the AI to target a team’s best players. So for the Lakers, not only will they run pick & rolls, but you can have them run exclusively with LeBron and Anthony Davis. There’s a new game plan option in the pause menu. Here, players can select between 8 pre-selected game plans that they can access in game through the On-The-Fly-Coaching panel (OTFC). Each game plan has default options already set up for them, so the player can pick a single option and have all the important details for that game plan ready to go. Here are two examples of game plans you can choose:
    • Play Through Star: This game plan will have ACE automatically select the best scorer on the team and only run scoring actions for them, both via plays and freelance actions. It also sets the tempo and rebounding choices automatically to accommodate your star’s playing style.
    • Pound the Ball Inside: ACE auto selects the best post scorer on the team and will exclusively run post scoring actions and plays for them.”

There’s a lot here, but I think I can more or less break it down into two categories that hopefully are improved by these changes. First, hopefully AI teams feel more varied now. It’s not so much that stars on each team don’t stand out, but you don’t really get the feel that the totality of teams are different. This is somewhat minimized as users go in and really edit team strategies and upload them for the community, but hopefully out of the box now more teams are different.

Second, hopefully this minimizes the need to have to edit your team before every online game. Again, if we can more easily save certain playcalls and such then this doesn’t even need to solve that problem, but the PNO fiends out there would love a way to be able to get more variety out of their teams.

  • “Starters and Bench Favorite Plays: This year we expanded the favorite plays to allow players to set up one group of plays for their starting unit and another group of plays for the bench units.”

Again, a great quality-of-life improvement, but please let us save this sort of stuff in more situations online.

  • “Moved player-specific plays and player-specific ball screens back to the L1/LB button. This was something many people were requesting so they could get quick access to icon pick control again. Favorite plays are now mapped to the DPAD.”

This may end up being what excites some people the most on OS, and I love this place for that. Again, 2K loves to make controller changes, and while some work out, others need to be quickly reverted.

  • “Play and freelance flow: As we have done every year, the play and freelance offensive flow has been greatly improved moving to next-gen. There are several actions that we just had a hard time getting to run smoothly in past 2K games, but thanks to the logic upgrades and vastly improved motion engine, everything flows extremely well in NBA 2K21 for next-gen.”
  • “Fixed AI players accidentally positioning themselves out of bounds.”

I love using the base sets without needing to call plays, so any changes that happen here I will be sure to scope out. It’s very rewarding understanding the spots on the floor and what cuts/screens get triggered off them, so I want to be able to use these freelance systems as much as possible.

And these systems can only be improved by the AI players staying, ya know, on the court rather than out of bounds. This specific improvement was hinted at with the changes to foot planting and the physics engine allowing the AI players to get their feet behind the 3-point line without you needing to do it, so it’s good to see this improvement is carrying over to other portions of the gameplay.

  • “New pick & roll spacing: New spacing code gives some of our pick & roll and isolation sets that extra adjustment on dribble penetration. It’s much more solid now but expect continued expansion on this module as the year goes along with our in-season play and AI updates.”

I actually don’t have a ton of problems with the pick-and-roll spacing beyond the AI players just holding the spacing for longer after you call for that spread pick and roll. If this means the AI players are better able to read the space (and don’t dive into the paint from the corner too soon!) but rather relocate around the perimeter, then fantastic.

There’s a lot here, what excites you the most? What did you not hear enough about with the AI? What are you worried about the most with the AI?

  1. Everything sounds nice. But this is nothing new to me every year. They're supposed to make their newest releases sound nice. I just want to see at least one unedited quarter played.
    Overall spacing has always been a issue with 2k so hopefully they made the court bigger or players smaller.  The screen news is welcome but will have to see it in practice. It's so deflating when you want to get online and play a pick up game with your friends only for every game be curry slide behind a screen all day. Online I just want to see a game of balanced basketball not a game dominated by certain OP animations
    1. Will the ball be tangible? Or will everyone will be able to dribble where ever they want without fear of a turnover.
    2. Will they actually call charges? Or can you spam the paint off the dribble.
    3. Will they call foul on jumpshots? Or can you continue to do reckless turbo closeouts.
    4. Will they call foul on defenders for running into a jump shooters landing space?
    5. Will the passing rating ever matter? Or will Enes Kanter be able to pass like Jokic?
    6. Will they turn down the speed and accuracy of long passes? Or will every team have the ability to run fast breaks like the 87 lakers?
    7. Can you pick who your help defender will be consistently?
    8. Can you choose which player to help off of consistently?
    9. Will defenders who you put in the gap or leave him defensive setting hang around the paint to protect the goal? Or will they still guard their man out at the 3 point line?
    10. Will speed matter in the half court? Or will 2 man animations turn 40 speed centers to 95 speed guards.
    11. Will the vertical rating matter? Or will Boban still have a 40 inch vertical at times?
    Great breakdown as usual Chase:
    Some of what i've heard sounds ok but we've seen this movie before. At this point i'll let you guys test things out and see how it goes. I skipped 2K21 thankfully and when I sit out a year (especially one this bad) I dont come back until a developer has dealt with 70% of their Legacy Issues:
    Here's the list I did last year: https://spgmg.blogspot.com/2019/10/top-20-legacy-issues-part-1.html
    1. Saying transition Defense is fixed is one thing. FIXING IT? Something else entirely.
    2. "The auto-switching logic was refined to reduce bad switching instances" Wait, What? So basically it will only switch at the end of games when I least expect it. This simply won't do. We need a No-SWITCHING option that's 100% please and thank you.
    3. No more suction screens? Good call. The interaction looks to be much better.
    4. The Return of Charges? If this is true its really, really good. Fingers crossed.
    5. Blocking Fouls are back? WOW....More great news IF TRUE.
    6. Guards move like Guards? Big like Bigs? We'll see...but again, thats a RERUN.
    Soooo what about the AI Bailout Fouls, lack of Deflections out of Bounds, Steal Spam, a Static Protect Ball, Pass Variety, Neutral Outcomes and finally separating Contesting from Blocking? Is the offense still recovering virtually every great defensive play that results in a loose ball?
    What about relevant Coaching Options and more importantly can we know what they do? What good is Jordan Rules if we don't know how it works? We want the ability to mirror the subs of our opponent like in reality. We also heard zilch about Play Now Online.
    I really hope you guys have fun but what i've seen isn't nearly up to my NEXT-GEN expectations. Better graphics is cool but GAMEPLAY IS KING. I'll wait to see what 2K22 has to offer.

    You were right all along. Ha
    Ideally it should be set that when you switch to limit transition that your players start to retreat back on defense once the shot is released. If they would add a rebound setting to each player as an offensive and defensive setting. You could put it to crash board or get back on defense on shot release. This would kill transition buckets, and also prevent all the bs offensive rebounding in the game.
    Good Stuff Chase ...great read and some really good analysis or relatic expectations of improvements mentioned in the blogs...
    Like you, most of your reservations towards these alleged changes are valid, but at the same time your still optimistic with your expectations ....I concur
    now what I want to add to the conversation is that fact that the constant patching at this point is a double edge sword...2k needs to be a bit more stern in certain aspect of the game and sell us the game they initially envision....Not the version influencers and social medias want....and for the most part more than likely I enjoy the game far more before the 18 patches that followes
