Edwards was quoted early in the offseason about looking forward to more snaps in camp at OG. But I don't think he's written in there in ink or anything, in fact he might need to flex depending on the other pieces.
He got schooled a bit at RG too as you would expect from a rookie. So it wasn't perfect. Rams still might want his length on the edge we'll have to wait and see how everything fits together after the FA period at the least. I think after that we can start to make better projections on who will go where.
