Out of the South, Tennessee usually has the worst instate defensive linemen class, besides maybe Kentucky and now Missouri, which makes it very hard to go and recruit those guys. They are always having to go into Georgia, South Carolina, North Carolina, Florida, Mississippi and else to find help.
That's why Barnett and Mosley are so important in my opinion. If this state can begin to produce a few more defensive linemen, or something similar to this season where there are several legitimate SEC targets, it will go a long ways to helping there.
