DallasCowboys.com believes RB Phillip Tanner's chance with the Cowboys may have "come and gone."
Tanner fell behind Lance Dunbar on the depth chart in November, and never moved back up. DallasCowboys.com's Bryan Broaddus believes it was because of Tanner's struggles in pass protection, and even on special teams. That spells doom for a reserve back who's currently due $555,000 in 2013.
