Tarver seems like a nice enough guy to me. Sure, if he has cheated then it is wrong, but I don't see how that is related to how well he can fight or commentate. Tarver does both jobs very well IMO. I actually agree with Bilbo here, Tarver should just ride it out and his reputation will be fine. As for his private life, that is for him and his wife to decide. It's none of our business really and we don't know the ins and outs, so it is all too easy to pass judgment.
