If it’s the Basketball Hall of Fame and not the NBA Hall of Fame, why isn’t Christian Laettner in it?

Literally the GOAT college player of the modern era. Four year starter that went to the Final Four for four straight years, playing in 23 of a possible 24 tournament games (winning 21 of them). National Player of the Year. One of the most iconic buzzer beaters in the history of basketball. You absolutely can’t “tell the story of basketball” without him.

For kicks, he also won a Gold Medal (technically is in the Hall for being on the Dream Team but that obviously doesn’t count the same way), and was a legitimate NBA contributor for over a decade including an All-Star appearance.

I’m told that Al Horford is a Hall of Famer in part because of his 2x NCAA titles, yet the most decorated NCAA player not named Kareem or Walton isn’t in it? Explain.
