I seem to remember glowing reports about Demby, who I don't think can play in the league.
That said; we all watched Demby and he wasn't very good. Edwards is a delight to watch as he seems to know what to do and he doesn't get pushed around. I still think he's an OT and not a OG so he's playing out of position. But he's doing good work especially on pass pro (as one might expect of a natural OT). His deficit is on interior run blocking. But, perhaps that can be coached into him.
