I dont think they take Ruiz either, I think they get a player who drops to 17 at a position of higher need.
With that said though I wouldn't feel comfortable saying anything is definitive for the cowboys tonight. Theyve got to be one of the most unpredictable teams tonight and could go a number of ways.
They can get away without taking a C high, but this o line has a lot more questions than I think people want to actually admit. McGovern is an unknown, looney has been mostly a backup in his career, William's has been inconsistent, smith/martin have had injury concerns the last couple years. Adding a high pick would go a long way in solidifying the group as you could move McGovern or looney to a backup interior role and make William's a backup for both tackle spots.
