"I was under USADA 12 years", "You need to be careful" - yes, and DC was, this phrases are actually proving he cheated too. But he is smart enough with cheating, so he can speak like he is clean and Jones isnt. Very sad and unfair. He and all people know that he (and most top fighters) is on steroids. Its like bashing man who caught with not paying taxes with knowing you and everybody didnt pay it too.
Else, he speaks "The fight didnt for the title sicne he cheated, so Im the champion". And even if we assume he is clean (big assumption), but in the Rumble 2 fight he cheated, but remained the champion.... Opportunistic.
DC showed himself as coward and man without principles personality IMO, if he would be honest and pride, he wouldnt take this fake belt after beating and will fight for the vacant title.
