Don’t think the staff quit. Concerned that it’s a f***ing clueless staff on offense and has hung its laurels on a big HeaCOCK.
I asked this elsewhere, but what would the sentiment on CMC be if Heacock had been performing at Manning's level?
That is not to say I'm not content with what CMC has built, but if we're looking to take the next step, you start with looking at the offense, which is also more under CMC. I don't think CMC is a miracle worker. Just one of the first good HC we've hired, and one that in the past has shown to be keen to look at areas in need of improvement.
In general, it is viewed that you can scheme talent better on offense, or at least hide weaknesses easier than on defense. You can build a good OL from lightly recruited guys, see UNI.
Of course Manning has earned accolades, largely in the same context as Purdy- due to the very low opinion of Iowa St from decades no longer relevant.
