It's Weidman by a large margin. That's why Anderson wants no part of him. Ah, I kid, I kid. Weidman has great wrestling, solid offensive submissions, reach, and competent enough standup to survive long enough to get it to the ground. I'd say Belfort probably has the next best shot of any MW to beat Silva. I'd put Bisping's chances at virtually zero. Jack of all trades fighters, e.g. Bisping, Forrest, Bonnar, etc. have absolutely no chance against Anderson. You have to be GREAT at something, and seeing Weidman take Anderson's wrestling coach (Munoz) down in under a minute puts him in that category.
