The difference between Bo and Solich is that there was a noticeable downward trend with Solich's teams. Bo's are staying even keel, with the possibility of going up or down.
i don't see going from 7 losses, to 3 as a downward trend. I see 2002 as an anomaly. (honestly, had he been fired after 2002 no one would have complained). But, we fired a coach that had played for a MNC a few years prior, won conference championships, won a ton more games, and most importantly just fixed his one bad season by putting together one of the better defensive units we'd had in a while. Completely different scenario IMO than firing a coach that hasn't achieved much outside of winning most of the games he's supposed to win, and losing a few more in the same category.
I always laugh at those who think coaches would cringe at the thought of getting paid 18 million dollars over 5 years to coach at a top 20 program because we fired a 9 win coach prior to their arrival. NO one expects us to land Urban Meyer or Nick Saban. They wouldn't come here if we had 3 straight losing seasons either. But, there are plenty of coaches that work on 1 year contracts for 500k or less a year that would jump at the chance to make 7 times that, guaranteed for 3-4 years. No coach worth having on your staff would shy away from the Nebraska job because of how the prior coach exited. In fact many would think coming into a winning program would be more appealing than taking over a losing one you have to entirely rebuild. In today's world where you often only get 3-4 years to do it...better to start out at 9 and work your way to 11, than to start out at 6 and still be expected to get to 11. Just my opinion. I know most people think those coaches would rather sit in their coordinator or mid-major job at 500k. Or continue to coach a bottom dweller SEC/Pac12 team with no chance of ever succeeding for 1.3 million over 3.5 million at NU.
