Yeah, I have to side with the Brit on this one. Bisbing is a tough dude, and Vitor just isn't the speed demon he used to be. I think his fight with Franklen is the last glimpse we're gonna see of that.
Bisbing is a grinder, and a very underestimated grappler. He'll strike is Belfort just fine. I don't think Vitor will KO him. I see this a grind match similar to Belfort vs. Tito.
Vitor is above and beyond the best striker Bisping will have fought. And his speed is definitely enough. Bisping gets caught by slow slow strikers.
