Considering how much talent and depth it'll have, Penn State's defense could be carrying the team this year once again.
However, it remains to be seen how Ted Roof's defensive style will translate on the field for the Nittany Lions.
After years of play-calling by defensive mastermind Tom Bradley, Roof comes in with an inconsistent track record and reasons for concern.
Roof has had his share of success, including coaching Auburn's ninth-ranked rush defense in the country in 2009 when the Tigers won the BCS National Championship.
However, the following year his young Tigers unit was mediocre at best, ranking 78th in total defense (406 yards per game) and 79th in scoring (29.3 points per game).
Considering his aggressive style, Nittany Lions fans should expect multiple blitz packages with an emphasis of swiftly creating havoc in the backfield.
While that sounds perfect, one thing that should kept in consideration is the Lions' young and sometimes fragile secondary.
If Roof is going to be extremely aggressive with his play-calling, he has to make sure that his secondary is up to the challenge if his pass-rushers don't get to the quarterback.
