they just seem like the type of team that loses some games when they shouldn't. They do seem to have a really good season every 10 years or so. Edited to add: I just checked their schedule...you are right they should NOT lose another game unless it's UGa. It still wouldn't surprise me if they got upset.
And as undisciplined as UGA is on D, I think GT will have their way with them just like they did last year.
That division of the ACC is shaping up to be a battle, as Miami, GT, and VT will probably end up w/ just one conference loss
