Happy Birthday, Coach George Karl! From your days as a scrappy NBA guard to becoming one of the league's most respected coaches, you've always known how to keep us entertained. Who else could lead the Denver Nuggets to an incredible 57-win season in 2013 and snag that well-deserved NBA Coach of the Year award—all while making it look easy?Your legendary sideline antics and sharp basketball wisdom have inspired countless players (and amused plenty of fans). Here's hoping your birthday is filled with laughter, joy—and fewer technical fouls than usual. Cheers to you for another year ahead!
