I can't imagine there would be 10 interviews.
First off, I don't know if there will be 10 qualified candidates with enough interest to interview. Note the term "qualified." I'm sure there are dozens of FCS and FBS coaches and coordinators who would leap at the opportunity, but they are simply not ready. For ever Mike Leach there is 10 Tim Brewsters
Second, The interview process is long and draining. I Don't know if there is a real date which Maturi would like to name his guy, but if he wants to save some face recruiting and beat other jobs to the punch, it will have to be sooner than later. I can't imagine a hire like this will require only one interview so the leaders will have to come back and interview again.
Third, I think anymore than six interviews would be overkill. I understand that you have to cover everyone in order to make the best decision, but if Maturi, the search firm, Mona, Bruininks, Dungy and whoever else does the right research they will have a much more targeted search rather than throwing out a net over 10 or more candidates and risk catching a Brewster.
