Not sure. I kinda like Weidman for the fact that a lot of older fighters tend to go downhill after a devastating KO like that. You can never count out Silva, though.
One thing is for sure - Silva has more to lose here than Weidman. At worst, Weidman is 1-1 against the greatest fighter ever and will remain very relevant regardless of outcome. Silva risks going 0-2, which would almost end his career aside from a few big-name fights here and there.
Either way, I hope it is a good one!
