I believe Dunbar has shared that secret with Brewster. I also think his job is secure (if he wants it) and that he wanted more help in getting the O scoring and winning TOP. I doubt Davis was brought in without consultation.
Like Schoodler and Husker say, strength up the middle. DT's, MBL (2), and safeties. Huge, but athletic, hard hitting, nasty with swagger. Blazing hard hitting speed flanking awesome middle strength. We are clearly headed that direction with this D and it will continue to be exaggreated and nastier. Mass plus velocity equals impact! Bodies in motion tend to stay in motion. Physics and football. Ooooh, yeah!
I think and hope (like SunGopher) that our O is headed the direction of USC. The spread can compensate for some drop off in talent when the system is down cold, but can miss big during the transitition (can take years). I believe we are on the cusp of having the talent to utilize the USC style of O and won't require a pure spread to compete.
When Brewster and the Gophers approach O and D I have mentioned we will be in the reload, not rebuild mode. It really looks to me that the Gophers can once again (after about 300 years) compete with anyone in the nation. Brewster has and continues to bring in talent beyond any reasonable expectation. The level of talent will continue to improve.
The new stadium will indeed be the scene of an incredible transformation. And no, I am not down on the program.
