McCown agreed to a deal with the Cowboys on Friday, Adam Caplan of ESPN reports.

EDGE Analysis

The Cowboys were fortunate for the latter portion of the 2016 season to have Tony Romo providing depth at quarterback to Dak Prescott, but it looks like there will be a competition in training camp this year to determine who will play backup. McCown, who has played the backup role throughout the majority of his career, will be entering his 14th season in the league. He backed up Drew Brees in New Orleans for the last four seasons, tallying one start in the process. He proved manageable in that lone start, throwing for 335 yards, one touchdown, and one interception. The veteran will compete with Kellen Moore and Cooper Rush for the role in training camp.
