Just so you know if the offensive caps for the players are too high on the 360 version the game won't play right for human vs computer play. I think playmakers discovered this back awhile ago. The players don't respond like they do for PC, XBOX or PS2 versions of the game. You have to lower their offensive ratings.
Im startin to sound like a broken record promoting this place....
check out www.operationsports.com I was just searchin around there and found a site that showed every needed sign/release and CAPs to update your roster post-draft
