I agree that LHW is currently weak, but MW? :blood We have Maravilla, GGG, Quillin, JCC jr, Pirog, Sturm and Geale in that division... I'd say it's one of the more lively ones.
The middleweight champs need to fight and cut out the bull**** defences, which in turn have created a bunch of fighters who look like contenders and are getting recycled across the champs.
