It's a difficult situation for Cal, I think, given two things:
1) It's very late in the year to hire a new Power 5 head coach, both from a candidate perspective and a recruiting perspective.
2) The cupboard is pretty bare at Cal right now, and it's not really a great situation. The Pac-12 is the best it's ever been, and competition for players is fierce -- and when you throw in Cal's academic requirements, it's an even tougher place to succeed. Gonzaga's Lisa Fortier-Tarpley (I think that's the right last name) has all the credentials, but like many successful mid-major coaches, would she leave an established program to struggle for several years at Cal and maybe wind up getting fired?
There's also a cost issue involved, as to get a quality coach at this point may be more expensive than makes sense, given the poor attendance and likelihood of two or three years of losing seasons.
Congrats to Lindsay, though ... hope it works out for her.
