I do think this was the best version of AJ that ever existed, and it wasn't good enough. But thems the breaks.
AJ at his very peak was a damned good fighter, nowhere near even the lower reaches of any ATG conversation, but that's hardly a disgrace. He's made a lot of money, has his faculties seemingly largely intact, good luck to him, he'll have a fantastic retirement and deserves it.
I agree I do think this improved version under Garcia needs more refining and he'll still be a force in the division. AJ's problem is he overthinks and never gets into a comfort zone long enough. Every tool is there but correct application at the right time is lacking. Maybe being based in America will bring it out of him.
Usyk doesn't stay in the same spot for more than 5 seconds. Fury would have a hard time pinning him down.
