This was a great fight. I was really bummed Lyoto lost; I was a big fan of his back then. Something that sticks out to me is how many roundhouse kicks to the body Weidman ate, and he fought like he was totally unaffected. Machida landed just one or two on Dollaway in his next fight, and that was enough to finish him.
As for all of the PED talk, maybe? Neither Weidman nor Machida really looked the part to me. Machida had that one USADA issue which maybe meant something, but USADA have proven themselves to be a bunch of clowns, so I don’t trust them too much.
As for Weidman, I think his drop in performance was probably due more to injury and the Rockhold fight. Keep in mind, before his fight with Rockhold, he spent a lot of time shelved due to injuries. Maybe USADA played a part, but I don’t think there’s enough evidence for it.
