Carr has been viewed as a massive disappointment as he has cost the Cowboys an arm and a leg. Carr early in the offseason looked like a cap casualty counting $12.717 million against the Cowboy's cap. His $8 million dollar salary is just a byproduct of the cornerback market the year Carr was a free agent. His last year on the Kansas City Chiefs was impressive to say the least; he tallied 4 interceptions, 39 tackles, and 15 pass defenses. 

His production was somewhat do to the Chiefs secondary but the Cowboys desperately needed help in the secondary so his presence was seen as a game changer. Last season Carr failed to record 1 interception. Carr only helped the Cowboys in the last six games of the season, games the Cowboys would not have needed so badly if he played better earlier on. 

Now it is not all on Carr but the Cowboys spent a large chunk of change to keep him around as a building block, his lack of production would create a hole in the lineup that the Cowboys have had trouble filling. They might have found the answer in first round pick Byron Jones but this has yet to be established. Carr needs to be a productive number 1 corner for the Cowboys to redeem any semblance of value. After the 2015 season the Cowboys will likely look to cut Carr's salary and spread it into later years.
