Named Mr. Basketball in 1966, Adolph Rupp once called Mike Casey the best money player he ever coached.
The basketball forward and guard was UK's 13th all-time scorer, with 1,535 points.
Casey became UK's leading scorer as a sophomore in the 1967-68 season. He averaged 20.1 points per game. Among his honors was an appearance on the cover of Sports Illustrated.
He will be missed.
