Obviously he's still with Ben. But who do you think got the most out of AJ from all of his former - and current - trainera? And how do you think his career would have panned out of he'd stuck with that same trainer all the way through ??
Aj really needed manny steward. Wilder as well. He would hsve turned them into way better versions of themselves had he been alive and got them early on.
I tried really hard to answer this but when you think about it, he's done nothing different under any of his coaches. He's the same fighter now as he was when he fought Parker 8 years ago. The only real change in his style came after the Wlad and Whyte fights when he became more risk averse. Otherwise he's got that Wilder stubbornness where he gets a new coach, pretends he's listening then gets in the ring and does the same old stuff he's always done.
