I know I am going out on a limb here BUT maybe, just maybe, Tito's back injury really was affecting his training and fighting?? Maybe he has decided that he really does want to be a fighter? His fight against Machida showed that he can still fight, and he was not totally destroyed like others were that faught Machida. If the "Tito of old" shows up, he may be able to work his way back to the top....
Would love to see Ortiz vs Silva again.
