Haven't seen anything like that since the 1954 Cotton Bowl, when Tommy Lewis, who was on the Alabama bench, tackled SMU's Dickie Moegle as he was racing for a touchdown. (I actually only saw a video of that one, years after it happened.) Alosi should be fined and suspended, if not fired. Looks like this kind of thing is what happens when the Rex Ryan mentality takes over a team.
It made me think of Woody Hayes slugging that Clemson player. A sad end to an otherwise great career.
