I think the suspension was a little harsh if the punch was the only thing he did. The actions after the punch were worse or just as bad and he has a history. A whole season though is harsh unless they are done with him after this and are just going to let him stay in school.
Sure it was a cheap shot but Haut inserted himself into the situation willingly. It justs shows the problem with a generation of athletes that has no respect for their opponent. Both are an embarrassment to their institutions.
