It's not about the camera angle as such, it's more about the manner in which the game view changes, both suddenly and randomly during plays/mid-play (not before the snap).
It affects my ability to see what's happening on the field (due to the aggressive camera shifts), which is rather important when you're controlling the players. Game controller direction is also affected due to the changing camera angles so what begins as a run diagonally will suddenly become straight, as the camera erratically shifts/rotates mid-play.
It happens in offline co-op (the only mode I'm interested in) and it's a complete play killer when it happens.
