I see Bisping pulling out the upset decision. Even though Belfort is dangerous, I do believe his best days are past him and Bisping is in his prime. It's still a bad matchup for Bisping but I see Belfort losing 2d and 3rd rounds, if Bisping can stay conscious and can stay on point. Bisping wants a shot badly and I think he'll bring his A game.
How many good days were behind W.Silva?
I think Belfort still have the best speed in the division, he is still very accurate, still have decent BJJ. I think he has enough to see off Bisping.
