I REALLY hope so. They did that in NFL 2K5. On top of that, there was pure interaction with other teammates. I can't tell you how many times (usually after an INT) where I'd go to make a move, and my own player would run into me and the ballcarrier shoved him out of the way. It adds so much realism when players interact with each other, no matter what team they're on. I feel like Madden has it's own "friendly fire" option, that they have turned off.
That would be really awesome. I also would add a lot of realism to the game.
