I've watched that fight 3 times now, and I think it was extremely close, but I do believe that Machida won.
I have to agree that Joe Rogan is terrible lately at his commentary. There was one flurry in particular, I think in the 4th round, where he said great right hand by Rua, and something about a high-kick by Rua, but when you actually watch the replay, the right hand flat-out missed and the high-kick was blocked.
I'm more disappointed about Lesnar pulling out of 106 and Alves pulling out of 107.
