IRVING, Texas -- The Dallas Cowboys passed on Johnny Manziel with the 16th overall pick, but they did add a rookie quarterback from A&M to their roster to be more than a camp arm. Well, West Texas A&M. Undrafted free agent Dustin Vaughan is known for two things: lighting up Division II competition and starring as the Christmas-sweater-sporting prima donna in a hilarious workout parody video. Not necessarily in that order. The 6-foot-5, 235-pound Vaughan’s goal for the next few months is to prove he’s worthy of the Cowboys keeping as a developmental prospect.
