Am I the only person who sees Britt get pushed from behind into Donald? Or is the thought that the smaller guy behind Britt isn't going to be able to move him? As a guy who is 6'4 230 I can attest to how easy it is to get moved by someone when you're running away from them and they're behind you. It is the ENTIRE reason blocking in the back is illegal. So either people are thinking that the little guy couldn't actually effect Britt's movement or they are COMPLETELY missing this fact...
I see nothing Britt did as wrong in the replay. I get at the time it would look that way, but how is it being missed with the ability to freeze frame as many times as you want? Britt gets shoved from behind into Donald and then does the NATURAL reaction every football player does when getting shoved out of bounds, shove the first person you hit to stop your own momentum. Just like they do to other players, cameraman, etc. (unless people get out of the way)
