NORMAN, Okla. -- The foundation of championship teams is often built upon the disruptive nature of its defensive line. The foundation of a quality defensive line is unearthed on the recruiting trail.

Cracks in both foundations emerged during the 2012 season at Oklahoma.

The Sooners finished 10-3 with a Big 12 co-championship but had one of their least disruptive defensive fronts in recent memory. And they’ll kickoff the 2013 with a very inexperienced defensive interior.
