For Cooper, a chance to resurrect a disappointing career to this point. Playing among the best offensive line in the league. If he can't 'get it' playing with these guys, he never will. For the Cowboys, a no-risk, minimal cost look at a player they really liked in the 2013 draft. The #7 overall pick, and a player whose abilities shown in college should fit perfectly in the Cowboys' blocking scheme. And a roster spot (Leary) that in all likelihood will be opening up soon. Low-risk, high reward.
