There are obvious ones, such as LeBron, Tim Duncan, Hakeem, and Shaq (although I’ve even heard some people claim that Shaq underachieved for a #1 pick).
But I’m curious exactly how many actually have lived up to their #1 pick status. There are some legends like Iverson and Kyrie that you could even question. Curious to hear people’s opinions on this, especially with Victor now in the league.
