I'm still not sure the Cowboys will draft an OT in Round 1. I think they are going to look hard at FA for a veteran OT and go to a strength of this draft in Round 1...at LB.
I understand Guard is also a strength in this draft. A pick at guard is intriguing and does make some sense to me. However, historically speaking the Cowboys don't do OL in Round 1. I think the FA period will give us some clues about the Cowboys perception of the whole OL situation.
My thought here is that the Cowboys are going to go for a SB this year. If that is true, you may bring in a player to develop but you need to have your OL solidified.....Now. If I am right, won't the Cowboys try to stock up on veterans and draft picks (but maybe not high ones) and try to sort out the best unit in camp? Typically OL's seem to get better as the players work together so I'm not sure how you put one together quickly. I just can't see that happening by counting on draft picks to get it done except as backups.
