I would say Bisping is a top caliber guy right now and may look to use his improved wrestling to dominate with his cardio, probably his best weapon. Vitor has never had an answer for the guys who used pressure a lot and made him react. Bisping while he has the ability to be well rounded isn't the smartest fighter on the roster and may stand with Vitor too long, so if that happens Vitor should more than be capable to outspeed and outpower Bispings chin and if he doesn't and looked like the slow Vitor you've got to wonder...
All those wars and beatings he survived contributed to Fedors later losses.
So if you agree that Bisping is a top tier guy, how does a loss to him show that Vitor is old and past it?
And we're going to have to agree to disagree about Fedor.
