It isn’t too often that a team’s sixth- and seventh-round picks from a year ago have a very clear path to go from backup players to real contributors on offense, but that is exactly what the Dallas Cowboys are hoping for with both RB Deuce Vaughn and WR Jalen Brooks. Both players have been getting valuable work in the team’s OTA practices, and have seen players ahead of them on the depth chart leave in free agency. The first domino to fall all the way back in March was last year’s starting RB Tony Pollard signing with the Tennessee Titans.
