I asked you to give me a definition of superstar and you gave me a list of names. If that's your definition then it would be impossible to have a superstar ever again until the end of time, because no one would be Kobe, Tim, Kareem, Wilt, Micheal, Lebron, Hakeem, Magic and Bird, Shaq, Ai.
Now let's talk about PGs. What is the most important statistical category by which PGs are measured? I think most basketball fans and knowledgeable people would say assists, since it's the point guard's job to run the offense and get his teammates involved, wouldn't they? Only two of your select few are in the top 25, and LeBron isn't a point guard and by your assertion Magic Johnson was a point forward (which is absolutely wrong*). If that's the case, then you don't have a single PG on the list since Michael, Kobe, and Allen Iverson were all SGs.
So no PGs measure up to superstar level? That's crazy! Don't tell me Jerry West wasn't a superstar. He's the logo for heaven's sake. By my thinking, of past PGs Oscar Robertson, West, Magic, Stockton, Isiah, Kidd, Payton and Nash all were superstars. Today there is no doubt that Steph, Harden, Russ, Kyrie and CP3 are all superstars. I think you need to rethink your definition of the word superstar, IF you even have one.
Sorry it's taken a while to respond, but I had to go to work.
* If Magic Johnson was not a point guard, then who was running the point for the Lakers? James Worthy? A.C. Green? Byron Scott? Kareem Abdul-Jabbar? No, they weren't, because Magic was running the point. You might compare him to LeBron and ask "what's the difference?" The difference would be that LeBron usually plays along with a point guard, who also guards the opposing PG, whereas Magic did not usually play alongside another PG and he guarded the opponent's PG himself. LBJ could accurately be classified as a point forward as could Scottie Pippen.
