Let's make this birthday one to remember.

63 years old (Born on October 13, 1961)

Happy birthday, Doc Rivers! You've been coaching greatness into existence so long, we're surprised your clipboard isn't in the Hall of Fame yet. From guiding legends and claiming that epic NBA Championship with Boston Celtics in 2008 (and bringing life back to a historic franchise), your celebratory fist pumps have earned their own spot on highlight reels.

As you swapped Celtic green for Clipper red starting from 2013—while deftly navigating every sideline emotion imaginable—you continue elevating teams through strategy and spirit alike. Another year wiser? We say you're just refining more genius plays. Happy Birthday, coach; here's hoping today is worth at least one technical foul for excessive celebration!
