My guess:
LT Olaseni
LG Ford
C Umana
RG Toala
RT Paulo
Paulo, Umana, and Ford all started last year, Toala played quite a bit, and Olaseni was a 4* JC All American. The "Utah OL is inexperienced" narrative is overstated IMO. Harding has proven himself time and time again, I have no reason to doubt he'll have the OL ready to go.
