Under Jerry Jones, the Dallas Cowboys trading down in the first round has been virtually nonexistent. Since 2007, Dallas has opted to move their selection down in round one just once. This happened back in 2013 when the Cowboys sent the 18th overall pick to the San Francisco 49ers for pick 31 and a third-round selection.
For Dallas, this unusual trade back actually worked out very well. Despite moving back 13 spots, the Cowboys were able to select center Travis Frederick in round one. Frederick went on to become a five-time Pro Bowler during his six-year career.
