Matt Barkley is entering his fifth year in the NFL and has already been a member of the Philadelphia Eagles, Arizona Cardinals, and Chicago Bears. Despite being a journeyman QB so far in his career, he could be an intriguing option to back up Dak Prescott next season.
Barkley isn't a starting caliber QB in the NFL, but he could be a serviceable backup. Of course, this is all based on what he was able to accomplish in 2016 once he was thrust into action.
The Chicago Bears had to turn to Matt Barkley after Jay Cutler and Brian Hoyer were sidelined by injuries. Barkley played in seven games and started six of those contests. He threw for 1,611 yards and eight touchdowns. Unfortunately, he also threw 14 interceptions.
Barkley certainly has his weaknesses as a player, but his performance last season as a starter showed the league that he can fill in if needed. The Bears are not a very talented team on either side of the ball, but Barkley did his best to make them competitive.
As a backup QB option for the Cowboys, he'd be surrounded by talent and there's no reason to believe he couldn't hold down the backup duties behind Prescott.
