You said it in a constructive way, which I could not. But I'm being petty about this based on my 12+ years experience utilizing special training. In fairness, mine is in Krav Maga and Kempo and not Judo etc. But again, one of the first things you learn is how to fall. Which is technically different then learning to tuck the chin which is involved. So I'm being petty and LITERAL with my take on learning to fall won't be effective
At the end of the day that is what I was implying. The tucking chin helps on plays like the Milano late hit in that first Buffalo game.
It's not learning how to fall really.
So in that sense it could help. But we're talking about a minimal amount of hits or tackles where that will help. Quite honestly the only hit that would have truly helped was the one where people still debate whether he had a concussion or not against Buffalo. Not so much against the Bengals and Packers.
But learning to tuck your chin doesn't require special martial arts training.
If they focus SOLELY on that, it could be effective
