I have a hard time seeing Alvarez offer it to either.
Suspect his first call is to Pritzlaff, who he knows as a Wisky assistant, and for better or worse the program slide is associated with him leaving.
Wouldn't be surprised to see him take a run at head coaches doing well at smaller schools (Bono, Schwab, etc.).
If he wants to go outside the box, why not call Jeff Jordan? Wisky national champ, very successful HS coach, would have an extensive recruiting network in Ohio.
IMO all of them make more sense than Taylor or Askren, from my guess of Alvarez's perspective.
Gotta remember too -- Alvarez is a meat and potatoes type. He will go hard after the best candidate according to his criteria, which won't include big splashy headlines.
