AnotherOD, Those are excellent questions; those are excellent points you make as you lead into those questions. Flaps2 adds "styles make fights", that starts to address your question as to whether this defensive scheme and "style" - stopping the run first, does not incur a greater amount of risk than say another similar style that defends the pass, and tries to stop the run, second. Perhaps that style would be more effective and incur less risk. You have used Georgia as your comparative yard-stick - well done. I will use the NFL for a brief comparative.
The NFL has [probably] as much three star-rated talent playing as the many five and four star talents playing (or a close equivalence numbers-wise). But wait, they are three stars, and not five stars. Perhaps they were mis-rated, or their coaches developed them (3 stars), or they studied, learned and developed themselves, or most likely , a combination of the above. The point is they are playing. How could they? Someone or a combination of people developed them and they proved themselves.
I don't believe our previous staff were effective developers; the current Duck coaching staff is very development-oriented, and they tell recruits and their families they are so. They must prove it every season/year, or the coaches (against whom they recruit and coach) and current players will show them to be liars.
If one compares heighth, weights of players, and the stars by which they are rated, how do we measure the difference? If could be by a schools' name; or it could be by the players' heart, dedication and determination, willingness to learn and apply, and their undeveloped athleticism/quickness, and quick-twitch fiber (that the coaches recognize). I believe that's what fans are generally describing and talking about. However, perhaps they are just snookered and have repeated a story (like W/our previous staff). The current coaching staff on defense have a ways to go, but are getting there. Our HC will coach them up, and they will learn from him.
What about our recruits? Perhaps we will sign a phenomenal class of players! We very possibly might, but even the five-star rated players must show up ready to learn and apply (and be in great physical condition). I like our coaches' attitudes, our players' attitudes and our recruits. They have made learning and hard teamwork fun. Although I like the "stop the run" scheme, the coaches must address the "air-raid" attack counters. If Coach Lanning is HC, I believe he will, and more (such as risk). He doesn't seem to let much grass grow between his toes.
You are on-track with your thinking and questions. Don't stop now! None of us want to be lemmings running mindlessly off the cliff. Success is all about thinking!
