If I was Joe Silva and/or Dana White, I would have Silva fight Rockhold in a champion vs. champion match up and put Jacare/Belfort against Weidman for the #1 contender spot. Weidman is still one good win away from being actually considered #1 contender. His match with Maia was just awful and one KO win over Munoz does not put him up at #2 in the MW.
And no, I don't think Rockhold is #2 either. Whole MW division is sorta mixed up at the moment with no clear #2 or even a #3 that would deserve an actual shot at the title. Had Bisping won he would have gotten it, but since Bisping got knocked out in a highlight reel fashion (once again) there's really no one I would want to see against Silva. Rockhold has at least the belt from Strikeforce that could be somewhat marketable fight and I guess Andersson would even take that fight. Or just have Silva fight GSP, but I guess GSP is too busy with Diaz and Hendricks for that to actually happen.
