Yeah, with hindsight I'd agree with the notion that Tarver probably outlasts him through sheer will after a bumpy start. He's tough enough not to fold if Kovalev catches him and has enough skill and size to really trouble Kovalev. Late stoppage.
I don't know, who wins prime for prime, but any version of Tarver would crush the version of Kovalev from Canelo fight quickly.
Version of Kovalev from Canelo fight, not only was old and shot, but wasn't actually preparing for that fight, only with beers, because he take that to lose for money(his words in instagram, i think you all know what he said). P.S.Btw, while there was ok to lose with KO, so Canelo was free to be aggressive, i think Kovalev was the better one before that last round for earning the money.
