IDK man. I mean, DPP and player roles are huge this year. Players on hot and cold streaks are really obvious, and I've seen the roles come into effect myself and it's been awesome. Santonio Holmes turned into Super Bowl MVP man vs. the Jets in my Raiders franchise, nabbing two spectacular scoring catches in the 4th to bring the game within reach.
The coaching schemes and positional priorities are also huge.
Were these things all in '07 and '08?
As for physics, everyone wants it but there are too many ideas about how it should work. Weight and momentum matter, but some folks say that if a 250 LB player hits a 190 LB player X outcome should always happen, or should happen at a highly favorable rate for the heavier player.
I don't disagree about height, weight, and speed as relevant factors, but I think it's easy to be too reductive about the possibilities and outcomes of physics based stuff.
I'm happy with appropriate animations. The way I have it set up now, Hillis WILL truck you if you're a DB. He WILL make your life hard if you're a smallish LB. McCoy WILL juke you out of your socks in the open field, and he will make you miss in the hole.
I'm good with all that stuff because it's believable from an animation standpoint.
I'd just like to see them continue to tune what they have. I'd like coaching strategies to work for each team rather than feeding off the user team's; I'd like a fix to the weird UFDA stuff, and perhaps enhance the defensive AI, which can still over blitz on late downs.
