Agree with Chrom. He hasn't even fought at HW, yet he's already talking about a superfight with the champ? Didn't he just get done relentlessly bitching about Cormier trying to do the same thing? It just seems like Jones is habitually doing the opposite of what he should be doing lately, no matter what the subject. If you ask him to fight Glover, he bitches that Glover isn't established enough. If you ask him to fight Gus, he bitches that he shouldn't have to fight him again already. If you instead pit Gus against someone else, Jones bitches about Gus' opponent. Now he's talking about fighting Cain, but just watch; as soon as the idea goes full steam ahead and starts to look like it might happen, Jones will start bitching that he's being pushed into it.
With all that said, I love the idea of this fight. Cain absolutely mauling Jones could be the only fight on the card and I would still pay to see it.
