LSU hasn't faced a defense nearly this good all season. Auburn gives up just 17.1 points per game. That ranks 16th in the nation. Auburn also is 11th in run defense with its NFL-caliber defensive line. 
Auburn freshman QB Bo Nix is getting better. He's surrounded by strong pieces. 
LSU plays Alabama in its next game. So the Tigers have to guard against getting ahead of themselves. Not so with Auburn, which needs this game to keep in contention to win the Western Division portion of the SEC. 
Auburn has covered seven of its last eight games.
This should be a highly competitive game just like the past three, which were decided by 1, 4 and 5 points.
