Let's call lower weight 140 and below. The best fighter p4p in those weights IMO is Lomachenko. Other top notch guys are Inoue, Estrada, Sor Rungvisai, Garcia, Donaire. But Davis is the most naturally gifted lower weight fighter in the world. He has that explosion and trigger that you cannot teach. Dude has talent coming out of his ears. It's too bad that Mayweather is ruining his career. And basically ducking all the top guys in their prime like Mayweather did. The one thing Mayweather should be teaching him is work ethic. That is something Mayweather was never short on. Davis likes to show up overweight and slack on training. Somebody has to get this kid in there and teach him the fundamentals of boxing and professionalism. If he ever gets those down pat watch out.
