most athletic? could be. but mayweather is on par with that specially with regards to reflex. but definitely RJJ as a whole package, pbf doesn't have the power that beholds both arms of rjj that's one thing. if there's frailty on rjjs totality as a boxer, it could be his mind as it has very poor ability to adjust, also his chin is something really not admirable. after he losses the once vaunted supernatural skills he have most specially his reflex maybe due to combination of age and too much weight shifting, he was exposed as merely an ordinary boxer and without the capability to adjust his style the rjj once we knew is long gone. I personally prefer him retiring than to see him get laid his a** on the canvas again further degrading his legendary status.
