Their defense is definitely improved this year, but a little perspective on that...
In three games against Eastern Illinois, Rutgers, and UConn, they gave up a total of 3 points (1 point per game). In those games, they gave up 116 total yards, 145 total yards, and 75 total yards respectively, for an average of 112 yards per game.
In the five other games against Ball State, Maryland, OSU, MSU, and Nebraska they gave up 174 points (35 points per game). In those games, they gave up, 398 yards, 383 yards, 520 yards, 442 yards, and 514 yards respectively, for an average of 451 yards per game.
Eastern Illinois is FCS and 0-8 on the year, while Rutgers and UConn are arguably the worst FBS schools in the country. So when they have played any team with a pulse on offense, it's been a little bit of a different story.
The bad news...we don't really have a pulse on offense. However, this is by far the worst defensive team we have played since UNLV so there may actually be at least some signs of life on that side of the ball for the first time since September.
