Tyrann was kicked off of LSU's team for marijuana use. He is a college student. Many college students do this. Most LSU students drink to excess. Because he behaved like a "regular college student", he was treated with prejudice and disdain, and ultimately with hypocrisy. Honey Badger deserved better.
This is not LSU's doing. Pot is on the NCAA's list of prohibited substances list. LSU couldn't have looked the other way even if it wanted to. To have done anything other than what they did would have risked forfeiting every game that he ever played in.
Oh...and he isn't "just like every other student". Playing football at LSU is a privilege. In order to enjoy that privilege, one must play by the rules...rules that are largely set by the NCAA. It was he who selfishly put LSU into a bad situation.
