Yeah, this should be a good one.
I couldn't really get on board with Vitor vs Weidman, once I knew Vitor would be off TRT and get inevitably rag-dolled. I was excited for Machida vs Weidman, until they got in the cage together and Weidman looked like he was two weight classes above Machida. Dude is a just a huge, solid MW.
Rockhold should end up being his toughest test to date due to his size, strength, and overall well rounded game.
With that said, I think Weidman takes a decision here. I don't really see Rockhold KO'ing him. I haven't really seen Weidman get legitimately wobbled by anyone yet, and he's faced some of the best strikers around. So until that happens, I gotta believe he has a solid chin. Though it there's a MW that can do it, it's Rockhold just based on pure punching power. But if he can't rock him, Weidman will out-wrestle him on the way to a decision.
