Guyton has been really good so far and all indicators are the arrow is pointing way up for him. Dude has totally changed his body too. He needs to stay healthy and if he does, we'll be fine there. I also trust these OL coaches. Adams and Riley are top-notch.
RT is another story altogether.
I do think one of the moves we'll make before Week 1 is a proven swing tackle, one with starting exp and I absolutely won't be surprised if Steele is finally benched at some point, maybe even the first month of the season.
