So I wanted to get some kind of data for you to help explain. But when I put into the search engine: What would Kemba's stats be if he was allowed to shoot 38 shots per game it couldn't compute. Sorry. You are totally disregarding the allowances and leash Pistol was given, especially in college. As far as NBA stats go Kemba Averaged 22 last year. Taking 11 less shots per game than Pistol did in his ONLY season that he won the scoring title. So to your Scoring leader question: if Kemba had the freedom to shoot 28 shots per game, 11 more than he did last year, would he have been the scoring leader over Harden at 30.5. I think you can answer that one.
As for some of your other questions.
As for that NBA 50th anniversary team, that was in 1996. Pistol wouldn't have a chance of making a Top 50 22 years later.
Skill question: Kemba has Pistol matched or beat in almost every skill category. He lacks his length but more than makes up for it in speed, quickness, explosiveness, strength. His IQ and creativeness are equal or better. His perimeter jumper is probably now better than Pistols, however in Pistols defense it didn't make sense to expand his jumper in a non 3 ball era.
The answers to the All NBA questions are unknown. If he gets traded to a successful franchise (Please let it happen!) for the next 7-9 years I could see him leading a team, upping his Assists and having more room with shooters around him to get better looks, then maybe. But 1st team is probably not likely. He unfortunately has some historically great PG's/Gs in his era, from CP3, Westbrook, Harden, Lilliard, Steph, Kyrie, Wall, DeRozan, Lowry, Parker all extremely great PGs, probably at the very least 6 HOFs, all on highly successful teams (which matters to voters). But there is an outside shot of getting a second or third team all NBA by continually dragging an abysmal Charlotte team to the playoffs as he has done before on his back. So those All-NBA questions that you raise are debatable. Unless of course Big Mike decides he gets to shoot nearly 30 SHOTS PER GAME! Because then he will be on the ALL NBA first team for the next 7-9 years...
Oh, and to your point of Kemba not doing anything players haven't done before, Name one other player who lead their team to two championships on an 11 straight postseason single elimination games, while also collecting to MVP awards??? Certainly not your boy Pistol.....He didn't win very much.
