How many fighters are there in the SF Middleweight division? 5? 6? Rockhold really doesn't have a whole lot of competition. I know Dana says there's no chance of UFC guys making the transition to Strikeforce but the UFC Middleweight division is so deep there are some really talented fighters that will never see a title shot. Sending them to Strikeforce might be best for everyone. With that said, Souza may be the biggest challenge that Rockhold can face in Strikeforce.
