re: Why is the uga vs ND game not as hyped as LSU vs Texas?

Because it's already been a recent occurence. LSU-Texas had the advantage of two top-tier programs who had some history but hadn't played in a long time (to most people's recollection) that happened to be border "rivals". There's a lot of storyline there to mine.

UGA vs Notre Dame is top OOC draw, but the history (recent and historically) isn't the same. The fact that they played, already, two years ago, removed the fresh "I've never seen it" angle that existed. Now, it's somewhat like the random week 1 kickoff games.
