Big Manny Frostoballess' philosophy isn't dumb on this and he has repeatedly communicated in his various pressers he isn't abadoning what he feels works and what got him here.
Put it another way (to an EXTREME DEGREE): US military doesn't change training and tactics because of the recruits we get/have. You will broken, you will learn, you will succeed or ypu will not be here and we will move on to the next.
Big Manny's philosophy is "system first" not "player first". JJ, Saban, Meyer, et al think exactly the same way. Yes they tweak, but only after the base system is established.
Big Manny KNOWS he has the time, because he isn't getting fired for at least 4-5 years, to install what works.
We all need to settle in for the long painful ride rhis is going to be.
