The Dallas Cowboys, along with most teams, say that they have their draft big board set ahead of the NFL Scouting Combine. We know that's not true though, because those who light up the combine typically get drafted higher than they were previously projected.
Further, if boards are already set, why even have the combine? If it isn't going to change anything and teams really "turn on the film" as a sole means of grading players, why collect measurables?
Thus, the NFL Scouting Combine can and should change a lot when it comes to draft boards, but teams do indeed already have a pretty good idea of which direction they'll head. That's particularly true in the first round because blue-chip prospects are easy to identify; we know a player like South Carolina defensive end Jadeveon Clowney is a top-tier player, regardless of what happens at the combine.
Let's examine a few players the 'Boys will have on their short list in the first round. You won't see Clowney or any other surefire top 10 picks. Rather, the following six players are all legitimate possibilities for Dallas in the first round of this year's draft.
