This might be of some interest, although we won't know anything useful about Georgia before we play them, most likely.
I think the big difference is that Georgia comes into 2017 in a rather stable situation (2nd year of a new coach's program, 2nd year starter at QB, deep RB crew). ND, by all accounts, is just starting over again with new coordinators and systems.
UGA's offensive line wasn't great last year. A lot of reporters around the team expected more mix-and-matching during spring practices this year, but apparently it's been pretty steady. Reports (including this linked one from ESPN) suggest the UGA offense, in particular the running game, is pretty well ahead of UGA's defense at this point.
