I think even fourteen guys is a lot when you're talking top-flight fighters who need a lot of attention.
Roach did not make Manny good. All trainers are overrated. I give them credit for continuing a standard and helping a fighter stay focused and sharp. But the fighter is the great one, unless a trainer develops several fighters from when they were young and in the amatuers.
i think he trains alot of fighters- but many of the name guys dont train with him year round, only in the months preceeding a fight, like chavez. whereas pac and khan are year round.
At the same time, take a guy like Judah and his incompetent father. I believe Judah's father hurt him tremendously. Judah had all the physical tools to be a dominant force. Instead he was an inconsistent performer who always received incomprehensible "advice" from his chief cornerman. It's a shame. I'd bet Judah could have been so much better if he had a better coach (Roach, possibly).
Roach did make Manny good. If you compare what he was back in the Philippines, Manny would have never been able to even fight the way he did against any welterweight if he didn't have Roach teach him footwork, defense and how to use the right hand. That right hand was developed by doing useless in fights five punch combinations using only the right hand so that he could easily change right hand trajectories during exchanges. Not every trainer has the brains or boxing knowledge to even devise training methods like that. That said, Roach has always said that the only reason he's this famous is because of Manny. Even then, you cannot discount how good Manny has become because of him. Heck, if Roach wasn't there, Hatton would've won against the jab-jab-straight left cannon that Manny was years ago,
He's making serious money now off Pac alone, he dosent need to have an extensive stable at this point.
