Nebraska fans are cute. Obviously Nebraska was a good program from the 60s thru to the early 2000s (for the most part). If this was the late 90s/early 2000s then absolutely you'd think that Matt Campbell would be interested in the job. But right now? Since 2015 they have exactly 1 winning season and the rest are below .500. They have fallen completely off the map and their recruiting rankings are slipping a bit where they've gone from top 20 for most years in recruiting to now being outranked by Iowa State. When you are recruiting 16 or 17 years olds right now, recency matters. They are so young that they're barely going to remember the last time Nebraska was actually good.
Scott Frost was also a weird hire for them - he had 2 seasons of HC experience under his belt and 1 was undefeated, but the other one was 6-7. He is from Nebraska and played QB for Nebraska. Sorry to say but he set their program back more than the fans realize. The fans still believe that they're in the 90s or even early 2000s but I think they're in for a rude awakening.
CMC has built something in Ames where he has amazing job security right now and is actually beating Nebraska at recruiting. So what is it in for CMC to go to a school that has fallen off the map, and now has worse recruiting rankings than what he has now? With Nebraska fans since they still believe they're winning championships in the 90s and they're pissed because of what Frost did, they'll fire Campbell in 3 years even if he had some 7-6 years in there. It makes no sense.
Nebraska should go after someone like Bill O'Brien who already has Big 12 and NFL head coaching experience. They should be hiring a high profile OC or DC like him especially as he used to be a head coach at the highest levels, recently.. and is the OC for Alabama. Hate to say it but he'd have better luck in Nebraska recruiting a good class than CMC would.
