ESPN in recent years has pulled in celebrity guests during its popular Saturday morning pregame show, “College GameDay,” and they typically have a local connection to the site the traveling show airs from each week.

This week it’s former No. 1 overall draft pick Bill Walton, who is known recently for being a commentator on ESPN. Ben Bolch of the L.A. Times reported that Walton will be on the show on Saturday as it’s televised from Southern California ahead of the Oregon-UCLA game.

Walton, known for his off-the-wall reactions, stories and descriptions during games, is a Naismith Memorial Basketball Hall of Famer and a former NBA MVP and one of only 4 players in the history of basketball to have won multiple NCAA and NBA Championships.

He returned to ESPN in 2012 as a college basketball analyst for Pac-12 games. He originally joined ESPN in 2002 as a lead analyst for ESPN and ABC’s NBA coverage, according to his ESPN bio.
