Greg Robinson would be a slam dunk. We could start him as a rookie at RT, or flip him to LT if Okung got injured again. It would also allow them to start Bowie inside at LG. Of all the draft choices, he would be the biggest difference maker and would eventually replace Okung if they couldn't agree to a reduced salary.
LT Okung, Bailey
LG Bowie, Carpenter
C Unger, Jeanpierre
RG Sweezy, Schilling
RT Robinson, Hauptmann
