this weight bully shit is silly. Pereira is another example, and a good example of what a man without excess fat and muscle mass actually weighs. most fighters, and athletes for the matter, are carrying excess muscle, excess fat, or both
the vast majority of the UFC heavyweight division, if not all of them, could make 205. a decent portion of them could make 185. khamzat can make 170 but he would have to lose almost all of his muscle mass to do so and his cardio takes a hit. otherwise a very heavy water cut which, evidently, made the docs stop it
either way if khamzat can't consistently make 170 and colby still wants to run his mouth, fight at 185. it's that simple. colby losing at that weigh class would not affect him at 170 (assuming he doesn't get knocked out), and if he wins it would be big for him. but, it would seem he doesn't actually want to fight chimaev. and is more interest in the WW strap which makes sense.
either way this is all bitch shit
