GSP was in a mirror situation to Jones.
He dodged Woodley to fight Bisping, which was the easier fight against the more weathered opponent.
Whittaker was next, and GSP chose to retire instead.
But, the thing is, if you've already competed against the best for 10-15+ years, you've already accomplished everything there is to accomplish, what else do you really have to prove?
Would GSP or Jones gain anything if they'd fought Whittaker and aspinall? It would be a great feather in the cap at the end of a storied career, but it wouldn't really change the bottom line in terms of legacy and all time status.
Much as we want the fight, I think people need to understand such a situation from the perspective of a top fighter at the end of their career.
With that in mind, where this situation does change is money. Jones is in a position where he doesn't have to fight again. If the UFC wants it, they'll bend the rules to make it happen, if not, then he's out.
Which is a great position to be in terms of leverage, especially in a star deprived ufc.
That being said, I think it happens.
Probably depends on who wins the poatan magomedov rematch. If poatan wins, I could see Jones giving up the title and moving down.
