Bo would have lasted longer under other AD's, but he wouldn't be the coach at UNL today. He was always chasing the distraction. Before the texas game in lincoln, he was yelling at a fan who had a website about what they had said about the staff. This is hours before a big game and that is your focus? (UNL lost that game, btw..) Unfortunately for Bo, the guy he chewed out was connected to one of the top donors and the AD made Bo apologize.... making things worse. There were other examples of Bo focusing on distractions and many arguements over did they matter or not in the fanbase.
Also, Bo didn't like to be told what to do... if people had ideas, he did the opposite to prove he was in charge. That is how it felt to me. He wasn't reflective, only defensive. I also think he's proven not to be a defensive mastermind, but rather someone who knew Pete Carroll's system. He could replicate it but not evolve it. This has remained true at the lower levels he now coaches.
Bo would have done better than Riley.. no question. But if I had the time machine, I'd go back to Steve Pederson and suggest helping Solich with recruiting and some new assistants rather than throwing out a guy who was a good coach during the week and on game day. He just struggled in recruiting and being the CEO. So work on the recruiting infastructure and grab a few stud recruiters. I still think Solich was a better HC than Bo. That's probably why I say that.
