Every year since 2011 we've built a draft board here on Blogging The Boys populated with players the Cowboys have invited for official pre-draft visits or have otherwise interacted with. By necessity, the result is a “Little Board,” as rabbelrousr used to call it, because the board should only contain names the Cowboys had more than a fleeting interest in.
We know that the Cowboys traditionally whittle down the 450 or so draft-eligible players to roughly 130-150 names that adorn their final draft board. If we assume that they are legitimately interested in the players they’ve brought in for visits, or players that had a private workout with the Cowboys (and not just random players the Cowboys talked with on the sidelines of a pro day or a bowl game, or one of the 60 interviews allowed at the Combine), we could know about 30-40% of the players on the Cowboys’ board.
