I dont think it's the fact that people think he 'can't' I think it's more down to the fact he has been talking about this for years and never showed any inclination that he would actually do it until this most recent fight where he came in lighter than usual.
The guy has been shitting on Jon Jones whilst still fighting at HW for what seems like an age.
People are right to be sceptical about the cut. It's almost as bad as when Roy Nelson claims to be heading to 205 but never does.
Who wants a cred bet that DCs next fight is at HW and not LHW?!
Roy's obviously joking about going to 205. Although I think he knows he can make the cut, his belly fat is a trademark moniker of his and not only does he see it as part of his identity, he sometimes uses it as an advantage.
I think it's unfair to criticize Cormier for not making practice cuts when the guy fights at heavyweight. What is the point of getting down to 205 for one day when you're trying to prepare for a fight against Roy Nelson, a 249 lber, or Frank Mir, someone who might come in weighing 260 lbs? Knowing how long it would take Cormier to make the drop, practice cuts are a waste of time. He wanted to weigh as much as possible while not losing the speed so he doesn't fight at a disadvantage.
He knows he's a small heavyweight and he could fight 205 lbs, so why not talk shit to Jon Jones when in all likely hood, they're probably
going to end up fighting anyway? He could be trying to build up the rivalry for as long as possible so when they do meet up in the cage, it will bring a lot more interest on top of what that match-up already has.
