^^ The NFL limits injuries SEVERELY. They allow them, but they cannot be the focus of the game nor can they be "glorified". The NFL knows injuries are part of the game, but they limit the depiction of them in-game quite a bit. They can only be generalized and i dont think they can even be animated in real-time either.
I may be wrong, but this has been my understanding. This also applies to player personalities. This is VERY limited and NO player can be depicted in a negative way.
I wish the NFL was that strict when it comes to the OVERALL product itself and how it plays NOTHING like the game they hold so sacred.
