The UFC announced today that Anthony Johnson will move up to 185 pounds to take on Vitor Belfort at UFC 142 in Brazil. Here's a link to the article on MMA Junkie.
I think this is a good and bad move all in one. I think Johnson should be fighting at middleweight especially since he has such a hard time making weight at welterweight. But for your first move into a larger weight class I don't think he should take on a top middleweight like Vitor Belfort. I would prefer to see him take on a lower ranked fighter first before moving straight into the upper echelon.
However, I do think Johnson is capable of winning this fight. I'm already excited for UFC 142 now.
