Is the LSU D Overrated??

Okay, so here we sit at the mid-point of the season and yet LSU's "dominant" defense ranks near the middle of the SEC in nearly every statistical category.

Total Defense - 9th
Scoring Defense - 9th
Rush Defense - 5th
Pass Defense - 9th

Georgia's rankings:
Total Defense - 3rd
Scoring Defense - 8th
Rush Defense - 1st
Pass Defense - 10th

Here is some additional analysis from ESPN Research:
LSU's usually dominant defense has been somewhat pedestrian through the first half of the season. The Tigers are allowing 21.5 points per game, their highest total after six games since giving up 22.0 per game in 2000 (Nick Saban's first season). LSU also has given up 28.3 points per game in its four SEC contests.
