Nick Diaz used to be the king of Strikeforce's welterweight division, which led to an interim welterweight title shot against Carlos Condit (Diaz 1,2,5) and a shot against Georges St-Pierre for the UFC's 170-pound strap. But now it seems like he's done cutting the weight as he gears up for a return. In fact, the elder Diaz brother turned down a UFC fight at 170 according to Dana White.
The last time we saw Nick Diaz in the Octagon, he was fighting former middleweight champion Anderson Silva at 185 pounds. It seems like this is the weight he's going to stay at, unless he's looking for a fight at catchweight.
Nick didn't look small against Anderson Silva, but he certainly didn't look like a big middleweight either. Some of the men in the middleweight division are monsters (see Yoel Romero, Weidman, etc). Is Diaz sick of cutting the weight, or perhaps he doesn't want to fight at welterweight any longer because that's the division his brother will be fighting in (if he gets his $20 million)?
Lots of questions. Lots of questions.
