UGA absolutely has the D-talent and scheme to beat LSU imo. LSU's offense is playing at such a high level I'm not sure they can be slowed down, but UGA running the ball on O and with Smart they are a good matchup, even if they haven't played as well through the year.
I don't like Georgia in that game, but I don't dislike them either.
Since the SEC refs didn't call holding on either LSU or UGly in our games, the outcome may depend on which OL they let hold in the SEC-C. Which one does the SEC think has the best chance to win the CFP $$$ becomes a factor in my theory...
