Perhaps the most decorated brothers to play in the NFL, Tiki and Ronde Barber both rank highly among the all-time leaders at their respective positions. As a running back for the Giants, Tiki rattled off five consecutive 1,200-plus yard seasons before abruptly retiring at age 31 following the 2006 campaign. Ronde is still going strong, and is indeed one of the most durable players ever to play in the NFL; since 1998, he hasn't missed a game. With eight combined Pro Bowl selections, the Barbers have proven that they come from a truly magnificent gene pool. And they're twins!
