Summary: Coe signed with the Cowboys on Dec. 11 and played in three games. He was used in the dime packages as an outside cornerback and also played special teams. He finished with one defensive tackle and one special teams stop. He opened the year with the New York Giants and played for Miami before the Cowboys claimed him off waivers.
Why keep him: He has experience and decent size (6-foot, 187 pounds). The Cowboys will be short on cornerbacks with Mike Jenkins set to leave via free agency.
Why let him go: He is what he is. There is no upside in keeping a 29-year-old journeyman who has limitations in the roles he can play.
Best guess: The Cowboys will let him walk and hope to get better. They will need to address the cornerback spot behind Brandon Carr, Morris Claiborne and Orlando Scandrick in the offseason, either in free agency or through the draft.
