Agreed! That's what I want to see on a consistant basis. For most power backs, I imagine a 1/3 of their carries end with 2 & 3 defenders bringing them down. If that type of interaction is typical, their finally getting it. Add some struggling-for-extra-yards animations to that, and that's what I would expect to see if they're skipping on a natural physics engine.
But it doesn't look like the blocking has changed a bit. D-linemen still just seem to give themselves up. No attemps to avoid being engaged, speed rush and take a corner, fake a speed rush before an inside move, hand fight, nothing. It was funny to see someone refer to Tecmo, because that's exactly what it looks like... with better graphics.
But between that gang tackle and the recent Madden blog, they at least worked on the tackling. Now just get some mobility & variety in the blocking mechanics so more defenders can get near the ball and this can start looking like football... at least near the line of srimmage.
