I think resigning Saffold is the big key. But if not Noteboom probably gets a shot at guard which would give him experience before having to take over at LT when Whit is done playing.
I think Sully is back for 1 more season.
Not sure where Snead goes for depth if we don't resign Saffold. He did get Blythe for nothing as he had been cut by the Colts. I suspect that they will draft defense in the first round but could see one of the 3rd rounders being used on an OL if there a value there.
I do agree that a strong Offensive Line is key to the success of this offense.
