Top NBA players of all time

I'm not one to rank the top players of all time so I picked out positions and put my five best i think it is hard to judge who at their peak was better. Given certain situations and teamates each player would flourish or flounder against the other but here goes 1. Center: Kareem, Olojuwon, Shaq, Chamberlain, David Robinson 2. Power Forward: Duncan, Garnett, Malone, Anthony Davis, Giannis 3. Small Forward: Lebron, Pippen, Kevin Durant, Grant Hill, Nowitski 2. Shooting Gaurd: Jordan, Kobe, Wade, Drexler, Ray Allen 1. Point Gaurd: Isaiah Thomas, Magic, Paul, Curry, Stockton I left out Bill Russel, Dr.J, Charles Barkley, Shawn Marion, Jason Kidd, Larry Bird, Shawn Kemp, Jerry West, Elgin Baylor, Pete Marivich, Allen Iverson. Much ridicule follows the players from the 60s and 70s for their skill level, but they were restricted by officiating and rules that prevented them from developing creativity dribbling and such. Were they around today who knows how they would play and develop. Chances are they would be even better than they show on filmed record from their era. BI didn't know where to put Russel but he could easily be pf or center list. Barkely I just decided wasn't as good as those five though at some point in his career and those five careers he could have beat them. Dr. J could be on there over Nowitski, but Nowitski would probably win by modern play. Kidd could easily beat out Stockton, but stockton is all time assist and steals leader for a reason. I didn't go with Iverson over Drexler, but i could see a case for him. I think I'd go with Clyde though
