If he didn't convince people he was the real bantamweight champion the first time he beat Renan Barao, T.J. Dillashaw certainly did the second time.
Dillashaw wore down and dominated Barao at UFC on FOX 16 on Saturday night in Chicago to retain the 135-pound belt. He finished Barao a round quicker than he did the first time at UFC 173, scoring a fourth-round TKO (strikes) after a barrage that left the Brazilian limp against the fence. If that weren't enough, Dillashaw also took home a Performance of the Night bonus for his efforts.
