Jones wouldn't be surrounded by younger anything in the UFC heavyweight division. He's the same age as the champ and Gane is the only contender meaningfully younger than Jones who hasn't taken more damage than Jones over the course of his career. Jones tops the field at heavyweight by a wide margin (and historically any heavyweight other than prime Fedor) in speed, all-around skill, and fight IQ. How hungry Jones is is a matter yet to be determined; he had no hunger (and nothing left to accomplish) at light heavyweight by the end of his run there, but he's training like he's serious about heavyweight and he knows that a heavyweight title and a few defenses would be accomplishments that make him the clear GOAT.
Hopefully Dana White gets his head out of his ass and we get to find out where Jones stands at heavyweight. If he's genuinely hungry and given the opportunity, Champ 2022 is more likely than not.
