Well, I'll defer to you. I'm sure you have a world of experience as a head hunter for NFL H-C's and other senior staff, and probably can regale us with tales of guys who turned down sure things for a crack at the 'prize' and won.
Flores went through 4 interviews for a D-C job and had one firm offer. He was faced with a dilemma. Take the job offered or take a 1 in 3 chance. I'm sure he was confident facing off against two coordinators without H-C experience, and I have you to attest to that. But, something may have bothered him as the deadline approached. Why? he may have asked, given that I interviewed weeks ago, haven't I been offered the AZ gig?
