That's ridiculous.
Jordan was an absolute elite athlete. And we're not even mentioning his length and hands which allowed him to be so effective around the rim. While LeBron is a freak as well, there are certain areas where I think Jordan was still more gifted than him. I don't think LeBron for example ever possessed the grace and elasticity that Jordan had, which allowed him to move and shift his body mid-air in search of better angles. LeBron can certainly push people around more easily, but Jordan was able to achieve similar results by being more elastic I think. On the other hand, Kobe I would say was a level below in athleticism to both players.
Even in his second three peat Jordan was still a bull physically, and could back down almost any guard. All of this while retaining more than enough mobility. So that means that even in an advanced age he still possessed great physical attributes that allowed him to pack muscle without losing speed and explosiveness. Remember that most older players have gone the other way, they have lost some muscle to retain mobility. Jordan could do both, which shows how great he was.
