Time is cruel, and no matter how much joy an athlete has brought fans over the year, eventually they must hang up their jersey and head off to ... Las Vegas? After 16 seasons with the Cowboys, not counting a year off spent in a TV booth that's best forgotten, Whitten left the Pokes a second time to sign on with the Las Vegas Raiders. In Dallas, he racked up 1,215 receptions and 12,977 yards receiving, the second most of any tight end in NFL history. Beyond the stats were countless clutch plays by the big man — he's 6'6" — who was a favored target in do-or-die moments. A legendarily tough player, Witten played through a broken jaw in his rookie season in 2003, when he was named to the NFL All-Rookie Team. He missed one game then, and went on to start in 245 games for Dallas. At 38, he may have lost a step on the field, but he still shines in fans' hearts.
