Great pick. If someone told me before the draft the Cowboys would address the offensive line in the 1st round while still trading down to pick high in the 3rd, I would have been elated.
And one thing this team deserves the benefit of the doubt with: when they pick OL in the first round they simply do not miss. A lot of of the technique criticisms we are hearing about Guyton are exactly the same things they were saying two years ago about Tyler Smith.
Guyton has every single physical trait you want in a left tackle. There will be some growing pains early, but he has the look of a ten year anchor.
