The most overrated would be someone who got his legacy turned into almost a mythological folklore who made no errors. For as many people who love Kobe, there’s just as many who dislike him, call him a rapist, a chucker, egotistical Etc.. for every Chauncey billups or a skip bayless, there’s a Nicki Wright or Colin cowherd who criticize him.
The most overrated really is MJ. His legacy is damn near mythological and people act as if he never made a mistake, he never lost etc. every time Lebron is criticized, people say what Mj “would have/wouldn’t have done” and so forth. He’s damn near like a Deity to the sports world that did no wrong during his time in the NBA
It took years for people to come along and make MJ’s legacy seem human again.
