It's a tough situation with middleweight right now. Rockhold just lost to Romero. Gastelum won a closely-contested split decision and beat the former champ just shortly after he got choked out but lost to Weidman and was at fault for a no contest shortly before. Souza just lost to Gastelum. A very close one, but he technically lost. Weidman beat Gastelum but he decisively lost 3 in a row before that.
Man do I wish Mousasi was still around...but I guess what they will have to do is book another Weidman vs Gastelum fight now. The last fight is not even a year ago and it was a finish but I don't think there is a better solution to the situation we've got now.
Since I can't stand Romero and Weidman and am also not very fond of Gastelum I'm really hoping for Cara de Sapato to make a run for the top contender spots after his fight with Brunson.
