Happy Birthday, Coach K! You've coached Duke to four NCAA championships and led Team USA basketball to Olympic gold in 2008—clearly you're the master of turning hoops into hardware. Your trophy cabinet must be bigger than most people's living rooms by now!Whether it's guiding college stars or NBA legends, your winning formula never gets old—even if you do (just kidding!). Here's hoping this birthday is as legendary as your career highlights. May it bring more joy than a buzzer-beater victory over UNC—and fewer candles on that cake than points scored by Team USA.
Cheers, Coach!
