Let's make this birthday one to remember.

49 years old (Born on December 23, 1975)

Happy Birthday, Kirby Smart! You're the defensive mastermind who turned Alabama's defense into an unstoppable force back in 2009. Your strategic genius helped secure that undefeated national championship season—proving once and for all that offense might sell tickets, but your legendary defenses win championships (and birthday cakes).

Now as head coach at Georgia, you've continued to dominate college football with relentless energy and passion. From sideline intensity to epic victories on big stages—you've given fans countless reasons to cheer loudly...and opposing offenses plenty of nightmares.

Here's hoping this year brings you more trophies—and fewer gray hairs from nail-biting finishes!
