Re: So who starts at RG now?

Agree with 3030, probably Ancrum or Shelton.
Could even be, since Shelton is a lefty he goes to LG and Edwards shifts to RG. Maybe Shelton replaces Edwards at LG and Ancrum beats out Edwards at RG. Edwards becomes the super sub at both Tackle spots and Guard positions.
With our Rams we won't know until they line up for game 1.
