IMO, the key difference in CPJs O is that the scheme allows recruits that other schools would bypass to succeed. In major FBS (P5) football, we are the ONLY school that runs our offense, so we are at a recruiting advantage against other "option" teams, like the academies, when trying to find athletes that fit our system. On Defense, however, there really isn't a "triple option" scheme that "no one runs anymore." We will be competing against other P5 schools that run similar defenses for the guys that "fit" the scheme. So while, yes, the different D schemes utilize different player fits to different advantages, I still don't think there is a defensive version of the "triple option" out there for us to grab hold of. It's still going to come down to landing better talent on D, no matter what scheme we run.
I agree with you completely about the DFEI rankings. I also think that getting into the top 50 would help dramatically.
