I'm not upset with the patriots for letting him stay in. I'm just surprised the refs didn't stop the game when it was blatantly obvious that he was wobbly. Cris collinsworth didn't even mention it. I think in the future, especially with how much they stress player safety, a ref should use a his discretion to say if a player needs to be checked out. This is the exact thing the NFL says it doesn't wabt happening but they aren't enabling the refs enough
