I can say that the D-line is not the strength of the team, but even with what we had last year we made some stops given all of the time that they were on the field. If the offensive line pans out the production and points that will result may balance the weaker defensive front. Teams will run on us, but we have some help coming in from recruiting and from the S&C program coming along. Who knows what they look like after an off-season with CJP. They should have a better understanding of the schemes that CJP runs, and I imagine there will be more blitz packages in by then as well. I think that teams are made from the Jimmies and Joes more than X's and O's, but the pantry isn't completely bare and our team has some fight.
If all else fails, look at how well OU did with a JC defense. (Sarcasm)
