The Cowboys have reached an agreement on a one-year deal with free-agent guard Jonathan Cooper, according to a source who spoke with Todd Archer of ESPN.com (on Twitter). Cooper joined the Cowboys during the playoffs in January he was released by Cleveland. 
The former No. 7 overall pick hasn’t come close to living up to draft day expectations, but he did do enough for Dallas to give him a second look. He also looked pretty decent in his short stint with the Browns. Pro Football Focus assigned Cooper a 73.2 overall grade in his 183 snaps for Cleveland, a score that would have put him in the middle of the pack amongst guards if he had enough playing time to qualify.
Now that Doug Free is retiring, the Cowboys could slot La’el Collins at right tackle with Cooper taking over at left guard. At minimum, Cooper could be a quality depth signing for Dallas.
Not a terrible band-aid. They’ll have to look to the draft again to fill this hole. No $ in the coffers until they restructure a couple deals. Not sure why they haven’t yet they have the option to on at least 3 contracts – Smith, Crawford, Dez.
Still need to look at a FA CB. Carroll is a slot at best. And I hope we aren’t going into the season with Frazier at SS.
