What I'm saying is why is it only the big shot. Who is to say Vitor doesn't pick Bisping apart or just beat him around the octagon all night. Bisping hasn't proven he can out strike someone like Vitor. Now that doesn't mean he can't do it, but he hasn't done anything to make me think Vitor couldn't do the same to him.
Bisping has shown more skills with his jab and distance, an in overall technical ability, than Belfort has imo. Belfort has good timing, speed and power, which are all basically Bisping's weaknesses on the feet, so it will be very hard. It's not really a punchers chance thought. It's one big shot he needs, but it's a big shot he can wait for, pick and land with precision. I don't think Belfort will match Bisping's grappling skills and Mike can make this a boring fight and get the win. It's just going to take insane defence and awareness, which he hasn't shown in the past.
