IDK, watching the replay again in slow motion a couple of times it looks like Mangold starts diving at Talib just as he starts doing his 360 spin jump out of bounds. Guess we'll see what the league says in a few days.
That's what I saw too. Certainly worthy of a flag, but talk of suspension is silly. Considering the circumstances and the fact that he's an offensive lineman un-used to tackling, I wouldn't expect more than a minimal fine, if any.
As for the idiots throwing haymakers and shoving officials afterwards.............
