We don't know what the other teams were offering Dallas, but we have to give credit to the Joneses for being patient and getting the 3rd round pick. To me, the Cowboys need players at a bunch of positions who will play day 1 and become solid starters, at least. Barton is a potential pro-bowl caliber C. He is the best C in the class. Guyton is the 8th OT taken in the draft. Doesn't mean he can't develop into a solid starter, but I think the chances are Barton winds up being the better player when all is said and done. Of course, no one knows. Barton could also be a bust.
This draft is being dictated by the Cowboys lack of activity in free agency. The have a gaping hole at LT so they were almost forced into taking Guyton. The need a C too, but I am pretty sure they could go with Hoffman or even Bass if they had to.
I wonder what they would have done had someone taken Guyton in front of them? My guess is trade down again, maybe out of the first round.
