I played a lot of pickup basketball during my college years and after, and would often play against guys that seemed as athletically gifted as D1 players, but had only ever made it to the D3 ranks in college. After talking and interacting with these guys, my main conclusion of why they never would have made it at the D1 level or further was the basketball IQ component. And then there’s always players with the high IQ for their sport, but just reach a limit athletically (Fitzpatrick). That’s why people love to watch guys like LeBron or Josh, b/c any given moment you might witness something that the rest of us could only dream of ever doing.
