I think the biggest difference in a coaching search this year compared to year's past is conference realignment. Typically, the Arandas, Campbells, Whittinghams, etc. would be a no go. This year might be different, though. ISU is at their ceiling and their conference is dying. Baylor won't have a home outside of whatever 3rd tier the Big XII becomes. Whittingham may be a Utah lifer, though I wish we would have tried to get him instead of Riley. Here you get stability, $$$, and if you succeed your legacy will be celebrated for literally all of time with Nebraska fans.
Don't discount getting one of these guys as their conferences tank.
Aranda's situation isn't the same as he's in a much better spot post-realignment. Baylor is easier to recruit to, has plenty of money via donations, and will be in the hunt annually once Oklahoma is out of the picture. We don't have a realistic shot at him unless they have a bad year or something unforseen.
Campbell makes sense and will certainly be tied to the job.
Wittingham came in 2nd to Riley but he'd be a perfect fit. Sounds like he's only got a few years left in him at Utah so no shot there.
I'm surprised Narduzzi isn't getting any buzz. Pitt is a really hard job and he's done well. This will be a pretty telling year for how he is as a coach but he's a big ten guy. Seems like Pelini 2.0 and we can do better, but I'd like to see him at a major job.
