Our scheme isn't really that complicated. However the thing about our scheme is that it is very imparative that EVERY SINGLE PLAYER does EXACTLY what they are suppose to. In Bo's scheme it doesn't leave any room for someone to go off on their own and be a hero. Fundamental football lost us the BIG championship.
I'd say the second sentence of your post almost entirely contradicts then first sentence of your post which I highlighted. I would say being required to do EXACTLY your assignment for an entire college football defensive unit is very difficult.
Another issue I have is that Bo is constantly begging for guys to step up and make plays. Well, his scheme, and according to your statement is almost an ANTI-playmaker philosophy. Which is why I always found it comical, when the leading tackler of all time at Nebraska, Lavonte David, was repeatedly "out of position" and in Bo's words "swimming in it" or "lost out there"....f'ing comical really.
Thirdly, I've heard multiple, MULTIPLE, players quoted that the key to playing on this defense is spending the majority of your time studying the playbook and in the film room. This defense has been described by almost every knowledgeable person and analyst as complicated. I've even heard many, many players and outsiders describe this defense as "Bo doing things almost no other college defense does"........Sorry E, but if players, coaches and analysts all of whom are more knowledgeable of the situation than you or I are telling me it's complicated, well then my friend......
It's COMPLICATED.
