indeed. Oscar is truly my favorite player, even though he never played a minute for my fave team (Boston). I would have a hard time with best pure shooter...maybe Reggie Miller comes to mind. That motherfucker was a beast with the ball in his hands, and the more it mattered, the deadlier he was. yes, I would take Miller over Larry Legend, as astounding as that may sound.
Best pure defensive player: Wilt Chamberlain. No one else has ever come close to leading the league in both steals and blocks.
Best pure rebounder: even more than Rodman, Bill Russell. Ol' B-Russ went toe-to-toe with Wilt, who was at least 5 inches taller, and constantly dominated him, usually outrebounding him by 20 caroms or more.
I like the way you debate. Most "fans" have little if any education beyond the first game they ever witnessed, and also want to base their arguments on who did the most (i.e., the argument for Jordan or Kobe as best scorer) or the most often (i.e. Stockton for best point guard...but let's be realistic, when situations are tailor-made specifically for a player, then his stock plummets in my books).
You would make an interesting co-anchor on a sports-talk show, altho i highly doubt ESPN would ever take notice of either of us.
