It's not exactly the biggest free agent news out there, but the Dallas Cowboys brought back a couple of their own free agents on defense. Dallas re-signed exclusive rights free agent Cameron Lawrence and free agent Davon Coleman. Terms of the deals were not announced.
Lawrence is a linebacker who mostly saw time as a special team's guy, and it is there where he shines. Because of injury he saw some limited duty on the regular defense, but his contributions are special teams related. Lawrence was an exclusive rights free agent and came to Dallas as an undrafted free agent in 2013.
Coleman was an undrafted free agent defensive tackle last year who actually started the first game of the year against the San Francisco 49ers because of injuries for the Cowboys. He then injured his calf and played very little after that, spending much of the year on the practice squad.
This isn't exactly the signing of Dez Bryant or DeMarco Murray, but you got to start somewhere.
