Potential for Dallas pick trade

As with any of the other 31 NFL teams, the Dallas Cowboys have some holes on their roster; it just so happens that some of their shortcomings are on the offensive line and at safety, two areas in which this year's allegedly weak draft class happens to be particularly strong. At No. 18 overall, the Cowboys should have a number of players from which to choose that could start for them as rookies. Or, they can trade out of that spot -- either up or down.
