One of the few constants for the Dallas Cowboys for the past 14 years has been tight end Jason Witten. Over that span of time Witten has played in all 16 regular season games 13 times. The one time he didn't wast his rookie year when he only played 15 games.
Since joining Dallas in 2003 the Cowboys have drafted eight tight ends, and it still looks like they are looking for Witten's eventual replacement. Gavin Escobar is a free agent. The team also has Geoff Swaim and Rico Gathers (a Baylor basketball player turned tight end) on the roster.
