I think Bisping is #1 right now, even before fighting Vitor.
It's not even about he being, on paper, less skilled than the others, it's about his time has passed already for his shot. He is being around for while doing his job. He is far from being a fantastic fighter and this time we tend to revert to the "this fight doesn't sell because he does not stand a chance", but it's the guys turn, IMO.
He lost a controversial fight against Sonnen, who had the shot(twice) and Vitor had his shot at Anderson already and another present against Jones at 205 and if Vitor wins this one he'll be granted a third title shot since 2011. Attaboy, Vitor...
I will support your good point regardless of our differences.
