How has that West Coast style worked for the last 3 years against the Big Ten?  And that stud DC is defending against PAC12 teams.  Pass heavy offense VS Big Ten is a recipe for disaster, see NU 2017.
Let me elaborate then.  He would cone in with his wonky offense.  It would take minimum 2-3 years to see it start working.  Meanwhile, whatever DC he hires would have to scrap year 1 after realizing tbe Big Ten is harder physically, year 2 start over etc.  At best, we see more 8-9 win seasons.  That's his ceiling at a place like this, I promise. At Tech he had a fertile amount of athletes to really churn out yards and points, at Wazzu it's just now starting to click but it still isn't fully there.
And from a cultural standpoint he wouldn't like this job IMO, likewise this fanbase wouldn't like him.  It's a bad fit, just like Bielma would be.
