For as much hand wringing there is on HB about the offense, this season is going to hinge on the defense.
We can't allow mediocre QBs to throw for 300+ on us (I'm looking at you Mitch Liedner and Joel Stave). We can't allow teams to move the ball at will against us in the final 2 minutes of a game (BYU, So Miss, Illinois, Wisconsin, Northwestern). We can't allow crappy teams to run the same play 10 times and gain 20 each time.
I hope that we see some addition by subtraction on the DL. I hope that the coaching change in the secondary pays off. I hope that Lamar Jackson is the 2nd coming of Deion Sanders. I hope that the LBs stay healthy all year and take a step forward. But I remain skeptical until live action hits in September.
