Correction, he has not been given a free pass. He has been disciplined in every case where it was deserved.
As I have said elsewhere- in this case, TB's judgement may have offended you, too bad. He didn't ask anyone to read his twitter page. He hasn't broken any laws, or violated any athletic or student behavior codes. So the only discression is being rude, and immature, and for bringing embassassment onto the Basketball team. For that he has been punished.
You seem to suggest he was treated special, when in fact it is the other way around. If any other student at Bradley did what TB did, they would have not been subject to any penalty at all.
