Former NFL scout: Cowboys could trade depth NFL insider Pat Kirwan, a former NFL scout, assistant coach and player personnel director, recently went through all 32 rosters as if he were still in pro personnel and looking for solid roster depth.

He found 10 teams that had positions with enough depth that parting with a player could be an option. The Cowboys were one of those teams, and they actually have two positions with that type of depth, according to Kirwan.

“Keep an eye on the defensive line, where Dallas added Tyrone Crawford in the third round,” Kirwan wrote Sunday . “A number of teams would love a shot at 2010 seventh-rounder Sean Lissemore if he were available. As for the corners there are rumors Michael Jenkins is available, but the compensation would have to come way down to make sense.”

Trading Jenkins wouldn’t surprise anyone, considering they signed Brandon Carr to a five-year, $50.1 million deal in March and drafted Morris Claiborne sixth overall last month, but it seems unlikely that the Cowboys would part with Lissemore.

Although he was considered slightly undersized coming out of college [6-4, 300 pounds], Lissemore received a significant amount of playing time during the second half of last season. During the last 10 games, Lissemore recorded two sacks and 17 total tackles.
