South Alabama hung in against Auburn last season losing, 70-69, as seven-point home 'dogs. Right now Auburn isn't nearly as good as it was last season yet the spread is double-digits, which is too high even given that the Tigers are home. 
This game means more to South Alabama than it does to Auburn and the Jaguars draw the Tigers at a good time.
Auburn is feeling its way around after losing its top six scorers from last season. The Tigers brought in point guard Sharife Cooper, a five-star recruit. But Cooper has eligibility issues and has yet to play. The result has been chaos, turnovers and uncertainty at point guard. The Tigers haven't been shooting well, nor converting their free throws. They are extremely young with no seniors and just three juniors. 
South Alabama is 3-1 and playing with confidence. I see the Jaguars hanging in just like last season.
