Greg Robinson Seems Done At LT, Can He Play G?

Greg Robinson has not improved one iota at LT. I assume his last chance to avoid being a colossal bust, is a move inside to G. Is there any hope that he could at least become an average or better G?
The Rams must try and get a competent LT next year, it is crucial for the development of Goff. Sad part is, that player is currently NOT on the roster. I feel LT is the second most critical position on an offense.

Thoughts Herd?
