Cowboys are apparently up against the cap so don't hold your breath on any significant signings.
If that's the case there's not a snowball's chance in hell they pick three consecutive olineman. Holmes is vastly overrated in my opinion, no better than Costa or Bernadeau at center.
I like Thomas better than Cooper, but both should be regulars on Sundays.
Brandon Williams would be a inspired choice in the 4th.
Smith at #218 would be a steal.
