who's behind them? what experience do they have? what happens if you account for 1, 2 or 3 injuries? the good news is that there will be little loss of skill players (byrd, maybe lafell--ok both would be bad) so the O should be able to handle a weaker line. i was also going to write that the tough games will be at home, then i realized there's UGA and Bama on the road.
I expect Ciron & RJF to come back now, but that doesn't mean I'm not concerned that they won't. Also, while I think our lines will be good next year, my concern is primarily with the depth & maturity level/leadership.
