That's the purest way of judging whose the best. Just because someone has more success cause they got paired with a better coach (like Tim Duncan) or had incredible health for a long time (like Kareem Abdul-Jabbar) don't make them the best. To me, being the best is the guy who I am willing to put my life on the line for to win 1 basketball game. That's the purest way of judging who is better than who.
And based on that standard, T-Mac, Pippen, and KG are definitely in everyone's top 25. And in my top 10, they're definitely up there.
In terms of skill, talent, and athleticism, you can't find 10 better than McGrady, Pippen, and Garnett.
