Not really. I vividly remember watching Armstead for the first time back in 2013. All it took was 2 quarter, and I called my father and told him that we found our next Willie Roaf.
Concerning Fuaga, i'd move him back to RT if possible. I don't know what Peat is up to these days, but i'd bring him back and let him play LT and keep Penning for backup.
After the epic stinker Charles Brown put up in the 2013 Rams game, I was right and ready for a change. By halftime I was thinking “this team could make a Super Bowl push from the 6 seed.” I was that confident in Terron Armstead.
