I’d take a wild guess that most people aren’t aware of the fact that Louisville’s defense is ranked better on third downs than the offense. Before the Wake Forest game, Louisville’s defense was ranked in the top 25. The fact that they have fallen so far over the last two weeks is either a testament to the offenses they’ve played or a sign that teams have started to prepare much better for what they do.
I tend to think that it’s probably a mix of both but the more likely issue is the fact that they have faced offenses that really push the pace and the defense has run out of gas late in games.
