Georgia has a bad defense.
Gave up 38 to Clemson whose average is 43.
Gave up 41 to LSU whose average is 45.
Gave up 21 to North Texas whose average is 27.
Gave up 30 to South Carolina whose average is 31.
Gave up 31 to Tennessee whose average is 31.
All those teams have padded their stats against FCS teams and bottom dwelling FBS teams. The fact that Georgia is allowing anything even close to their average pretty much means your defense is not good.
See just proved your point
Held all of those teams below their average EXCEPT USC.
Not too shabby.
Secondary could use some work though.
