John Hollinger is leaving ESPN to take a position within the Memphis Grizzlies' front office.
Hollinger is best known for creating the Player Efficiency Formula (PER).
"It's incredibly difficult to leave ESPN, but the chance to work for an NBA team and the Grizzlies' new ownership was an irresistible opportunity," Hollinger said Thursday.
Hollinger was recruited to the Grizzlies by new controlling owner Robert Pera and CEO/managing partner Jason Levien.
Chris Wallace is general manager of the Grizzlies.
