Anyways, even before Jones won the heavyweight belt, I was doubtful of his ability to stay undefeated. His main assets which are his speed and length are no longer that advantageous at his age and in this division. So as much as possible Dana White will try to milk Jones before he loses or retires. Maybe we can see an Aspinall-Blaydes first before the interim belt holder gets his shot at the real title.
Sure, he lost some of the speed due to age and more muscle mass, but his performance against Gane was very impressive and it's fair to say that he did way better than anyone expected.
Every fighter will face a defeat eventually if they carry on fighting past their prime and don't know when to quit, but Jones is definitely not there yet. I think him mentioning retirement in the past was either due to slight mental burn-out (rather than loss of physical abilities) or just a negotiation tactic, to force UFC to give him more profitable fights.
Aspinall Vs Blaydes makes no sense. Blaydes is not there yet to fight for the belt and Aspinall has nothing to win there and nothing to prove - he lost to the injury not to Blaydes.
