Alabama had the best defense in the country and won the national championship. Teams like Florida State, Notre Dame and Florida had top-10 defenses and appeared in BCS bowls.

As players declare early for the NFL draft, we are getting a better idea of what each defense will be working with in 2013. Several teams will continue to have top-rated defenses, but a few others may surprise you.
We may be months away from the new college football season, but here are the early predictions for the top 25 defenses in the country in 2013.
