You have a friend in me 'bro. You should know that this is something I left in my feedback down in Orlando and something I mentioned to Ian personally as well.
2K8 didn't feature much collision detection in the run game, but 2K5 really shined here IMO. I'm not sure if the Ian and team can make big strides in this area this year, but I'm hoping we get a little something there. There was a push the pile animation in Madden 08 though it was infrequent. I'd settle for something like that this year. By the way, I'm primarily talking about colliding with your blockers. There needs to be animations for that.
