DBU had a rough go of it last year. LSU allowed 9.7 yards per passing attempt, which is completely unheard of around these parts. Now, the good news is, the talent wasn’t the problem, it was a scheme in which guys clearly did not know what they were doing.
Receivers ran free through the secondary, and LSU was prone to the big play as there were times when targets went completely uncovered. But here’s the thing… LSU was really good at coverage when it got its assignments right.
When we look at the ratings, the stat I like to look at is passes defended per attempt and per completion, as it shows how often the secondary is breaking up the play, particularly relative to the offense making plays.
