Here's LeBron's argument for why Popovich is GOAT

Gregg Popovich absolutely belongs in the conversation of greatest NBA coach of all time with names like Phil Jackson, Larry Brown, Red Holzman, Red Auerbach and Pat Riley.

LeBron James - with an upcoming game against the San Antonio Spurs this weekend - might cement the coaching legend as the absolute greatest with an argument he gave to reporters on Thursday night:

"He's the greatest coach of all time. I've said that over and over and over. You've got to be to do what he's done in the era of basketball when it's changed so much and he's been able to have a growth mindset and be able to change with the game. He's continued to build around Timmy [Duncan] and Manu [Ginobili] and Tony [Parker] and bring pieces in and out throughout his whole tenure.

"It went from a league where it was like, inside/outside. Like every time you bring the ball down, throw it to the big. Then it goes to every time down, pick-and-roll. Then it goes to every time down, shoot a three. Pop has been able to adjust every single time and still somehow keep those guys under the radar. I don't understand that."

That is a pretty great argument right there. It's not just all the winning and rings and more winning - it's the fact that he's done it as the league changed its style of play multiple times. Pretty sound reasoning.
