I don't want to get into this argument. But you don't learn the game of basketball playing in pick-up games. KG is one of the most fundamentally sound players in the NBA and he is getting no respect on this board.
Then don't presume that others lack knowledge or understanding that you have when they disagree with you based on an assumption (whether they played competitive organized ball I guess is how I understand you).
1. No one knows who played and who didn't and at what level here, we're all fairly anonymous on the internet (unless we take the trouble to cyber-stalk, thanks Facebook for making it easy!)
2. Playing at some set level isn't a requirement for understanding, plenty of players play and never understand after all (Hi Gerald Green! How was Russia, still cold?)
3. It is just a different appeal to authority in my book. You're attempting to give your argument more weight outside of what you can manage with your rheatoric so you bring up "playing the game".
In subsequent posts you're pivoting the issue to the difference between pickup and organized ball, which is entirely beside the point.
In the end this probably isn't worth going into all that much more than that. Just use your own experience with basketball to inform your opinions, don't use it to lessen others views.
I learn random things from my fiance who played women's basketball at a much higher level than I ever did. First one, girls are catty about freshmen taking their playing time. Second one, most people suck at post entry passing (hi Jameer Nelson!).
