As can be said for our opponents... let's consider for a moment the offensive juggernauts that are DUKE, Penn State, and who else did you play again?
Oh, and before you go "PSU>GA"... everyone knows Penn State's quarterbacks and receivers wouldn't make the team at Georgia. As for their respective OL and DL... do I have to go there?
