No, I don't think it will help the pass rush.
Why? Because as the sliders go right now, they both effect HUM and CPU on the HUM settings correct?
Well...with HUM Break Block at 100 and HUM Pass Block at 0, both the CPU and HUM Offensive lines are like the Berlin Wall.
There is a fundamental "cheat" in pass blocking.
One thing that WOULD help...Get rid of the freaking chop blocks/pancakes EVERY. SINGLE. PLAY. I'm really getting tired of seeing all of my defenders get flipped on their heads each play. And yes...it happens literally every single play.
Also, the Defenders running in quicksand is not going to be helped with sliders. There is a definite speed cheat right now towards the offense.
If you need proof of this, I'll gladly post some videos.
