Only abnormality I've noticed is that I'm getting called for roughing the passer about 2 times a game, without me even controlling it. Usually the DT will brush the QB coming out of an animation and the QB will just fall down.
Happened a few times in my Raiders/Pats game, Brady would get lightly tapped and he'd go into a ragdoll animation, fall down and draw the flag. So actually, maybe this IS more like real life
