Does Rockhold get a rematch? He never successfully defended the belt but he does have a win over Bisping and over Weidman.
Does Weidman get the fight? He is the #1 contender and already had the title fight lined up. He did lose to Rockhold but he also did defend the belt multiple times.
Yoel Romero coming back soon and he did beat Jacare (barely) and hasn't lost in some time. Also a PED user
Jacare? Lost to Romero.
A case can be made for and against all of them. Thoughts
