First off, why is Money not even on the list?!! Secondly, if we're talking most gifted/talented/athletic ability then the list should be comprised of nothing but brothas.
Roy Jones Jr. Unreal speed, reflexes and agility combined with tremendous power, only thing he lacked was a good chin. Did things in the ring that nobody else could do or would even attempt. Though of course there is a big question mark over Jones Jr due to the failed drugs test. Ali comes in a close 2nd. Speed was amazing for a heavy, so light on his feet, iron chin only thing he lacked was one punch power.
Corrie was definetly the most gifted fighter. One of the hardest punchers ever with blistering fast hands and impecable counterpunching ability and reflexes, he was a danger to anyone early in a fight, and he was doing all this while being only a part time boxer who never trained RJJ's athletic ability was incredible but he also trained his arse off in the gym. That's why Sanders is more impressive, because he never trained (as you could see it in his pudgy physique), he relied only on his physical talent Corrie managed to KO the best hw of our era, and rock his brother who probably posseses the GOAT chin on physical talent alone. He was a danger to everyone early in a fight (he'd alway gas and become weaker from the middle rounds upwards, due to his lack of training), Lennox and many other fighters with a name ducked him for a reason
RJJ. I really never liked him, but his physical abilities earned him the P4P fighter of the 90's. He also proves this to be true even more, as he reached him mid 30's. He was unable to be great or win big fights anymore, like others from his generation (Hopkins and Toney). Who were able to adapt, and generally relied more there actual boxing ability and ring generalship to win fights.
Klitschko fan's always do this. Sanders was a big puncher that could counter punch, no doubt. Name one A or B fighter he beat other than Wlad? You can't. Wlad also struggled to beat a free swinging Sam Peter and gassed out against Lamon Brewster, a don't think anyone's putting them on there most gifted list.
Pure athleticism it's either Ali or RJJ. Talent, then you could add SRR, SRL and a couple of others to that list.
