Happy birthday, Coach Mack Brown! Like a perfectly coached Vince Young breakaway in the 2006 BCS Championship game, may your special day be smooth sailing straight to glory. Sure—candles on the cake aren't quite as heart-pounding as fourth-quarter comebacks against USC—but they still light up smiles almost as bright.You've led teams through unforgettable triumphs and historic victories; clearly you've mastered time management better than any clock-running drive at Texas. Wishing you health, happiness and another year filled with winning moments both on and off the field—you'll always be our national champion quarterback whisperer. Keep hookin' those birthdays!
