If he got his visa issues sorted out so he could keep fighting in the UFC and hadn't robbed a Securitas depot while armed, where would he be today? Would he have won a title? Would he still be in the UFC?
This man had talent and I think he would still be relevant today if he didn't fuck up as bad as he did. 
He was still recovering from the whole getting stabbed in the heart thing when he robbed the depot, pretty sure he was done as a high level fighter.
