Beyond Joseph and Brumfield, what could be done is going with Korn or Peetz as a coordinator. Then a more senior advisor is brought in such as Ciarrocca as an analyst given his experience in the Big 10 and other considerations.
Riaola or Garrison OL. Possibly Davis as OL/Run game coordinator. Compensate him well. Sowder at Kent State is somewhat intriguing but like Korn he's not well seasoned IMO. It's quite a step up for both. At any rate, whatever combination there is the offensive line has got to be a priority. It HAS to be solid.
Bill Busch and Matt Davison have likely been working extensively behind the scenes identifying potential options. I'm still not thrilled with Helfrich or Herman coming on board. And if Chad Morris comes out of the woodwork to be our OC, I'll eat my socks.
