He is a headcase for several reasons. He is clearly not emotionally under control during games to the point that he has broken down in tears in between his tantrums. He tried to beat the crap out of a teammate for "bumping him" (Burfict's own words) during practice... the teammate? A 6 foot tall, skinny, walk on receiver, a bump from that guy made a 260 lb linebacker lose his cool?
And as for his combine times, I dont think they are a fluke at all. He is not some cut monster, the dude became a chub in college. The guy is NOT the athletic freak that people make him out to be. He has absolutely no work either and regressed as a player both mentally and physically since his freshmen year. And who does he blame for these problems? The media (who have been overly kind in my opinion), the refs, his coaches, but absolutely none of the blame falls on him, in his opinion he has done nothing wrong.
His play last year did not warrant being drafted at all, his attitude is even worse than his play, he looks like he has "let him self go" rather than get in shape for the combine, he takes no responsibility for any of his issues.
He is an undraftable player in my opinion. He will be out of the league within a few years and I wouldnt even want his attitude in the looker room.
