Although this legendary athlete was well-known to football fans, Smith didn't become a household name until 2006, when he was crowned the winner of the third edition of Dancing with the Stars with professional partner Cheryl Burke. A go-getter both on and off the field, the running back broke several records during his 14-year NFL career, played on three Super Bowl championship teams with the Dallas Cowboys and simultaneously maintained a stable home life with his wife and children. After retiring from the game in 2005, he had brief stints as a network studio analyst for the NFL, but had better success in philanthropic endeavors and as a businessman, helping to launch the retail real-estate company SmithCypress Partners with another Cowboy icon, Roger Staubach. And in a surprise move, he signed on to Dancing With the Stars the next year and charmed audiences with his charisma, commanding frame and deft footwork, even though he was initially considered an underdog. Elected to the Pro Football Hall of Fame in his first year of eligibility, Smith was presented by Cowboys owner Jerry Jones in August 2010.
