Canelo goes into fights heavier than Golovkin. Kell Brook is very big and middleweight is not a big jump for him. Weight will not be an issue in this fight. This is a competitive fight and a big step up for golovkin...at least from dominic wade. At least he isnt fighting a bum
Khan started at lightweight, was knocked out twice at light welterweight, and had no meaningful win at welterweight. Brook started at welterweight 12 years ago, is considered big for his division and despite lack of resume has one very solid win at the division and is ranked #1. GGG-Brook isn't a great fight but it's much better than Canelo-Khan
They are about the same but Khan's been knocked out a couple of times while Brook still has his cherry.
