Alonzo Mourning

Mourning underwent a kidney transplant in 2003 — donated by his cousin Jason Cooper — and returned to play in the NBA the following season, one of the most remarkable medical and athletic comebacks in professional sports history.

He was so dominant as a shot-blocker that opponents literally changed their shot selection approaching the paint when he was on the floor — a documented behavioral change that coaches in that era acknowledged openly.

His intensity was so extreme that teammates and coaches described practice sessions as more physically demanding than most regular-season games when Mourning was fully engaged.

He has served as Vice President of Player Development for the Miami Heat since his retirement — remaining with the only NBA organization he truly called home.
