1) To trade back you need a partner willing to trade up. Acting like its completely up to the Cowboys is dumb.
2) We dont even know who the top 15 players in the draft are right now. We can almost guarantee that at least one of the top 15 players from this draft will come off the board after our pick.
3) As another poster said, it doesn't matter the # of picks...just hit on them. Sure extra picks gives you extra chances to snag 'that' guy...but when it's all said and done, a draft that produces 2-3 starters is a great draft.
