The parallels between Belfort's career and Tito's career are eerily similar. They both were dominant during the same era, losses to Couture kind of derailed them, and both have the same stagnant era of productivity.
It depends on where his head is at. Like Tito, if he can get his mind right, he has the God given talent to be truly special. It just depends on where the mental aspect is and the dedication.
