I don't think it will be particularly bad other than it will be indicative of where there program really is. It will show: (1) they are not better than a 7-5 ACC team (whose best win is over Duke maybe?) and/or (2) their DC cannot stop the option even after having time to prepare (which based on Ga Tech's previous bowl games, I would think would be a bad sign) and/or (3) like the triple option, UM's offense is easy to stop if you have the time to prepare.
But as far being somehow having a bigger effect than any other loss, I don't think it will be a big deal. It may cause some of their high profile recruits to realize just how far they have to go as a program, but that will just as much because of their other two losses to end the season as the bowl loss.
But I don't think it will be a problem. I know the SEC this year was not what it has been, but I would still think any SEC team other than UK and Arkansas with time to prepare for the triple option would be able to handle Ga Tech.
