Tyrann Mathieu and all of the guys you named is that they played football. Tyrann Mathieu didn't play football this year and it will have been a year and a few months since his last game come draft time
I'll hit you double time on this one.
Lets talk Pac Man Jones.
was not kicked out of WVU, but he had a few run ins with the law while there. He had plenty of character concerns going into the draft. He was taken 6th, yes 6th, overall, 1st round.
Since then he has gotten in more trouble. He has missed 2 full seasons, 2007 & 2009. He didn't play a down in either season. Yet he is still able to play in the NFL. That's not even the biggest thing. The biggest thing is he keeps getting signed on. Talented players are hard to find.
