I think there's a good chance Vitor can put it on Weidman, but it would pretty much have to be in the first round. Vitor is absolutely vicious when he is fresh so I wouldn't doubt it if he stopped him.
If I had to put money on it, though, I'd say Chris stays out of harms way in the first round, then takes control from the second round on. Vitor fades quickly beyond the first round and also lacks the same confidence and explosiveness, which would all be worsened after Chris takes him down and beats him up.
