I read your list and I immediately think back to 2018 when we made lists for our next coach and how Frost was atop everyone's list and in large part it was because he was a homegrown guy who was having amazing success at UCF.
If we learn anything from our coaching hires since 1997, it is it really doesn't matter what the coach did at their previous jobs before they come here, it is not an indicator at all of what they will do at Nebraska.
-Solich was Osborne's protege and had been a part of the program for a long time.
-Callahan was an NFL coach and took an NFL team to the Super Bowl.
-Bo Pelini very successful defensive coordinator at Nebraska, Oklahoma and LSU prior to becoming Nebraska's head coach.
-Mike Riley Long time head coach with a lifetime of experience and always was credited to doing more with less at Oregon State. Since his departure from Oregon State it has proven just how hard of a job that is and Riley consistently kept them competitive and on some seasons got them on the verge of winning the conference.
-Scott Frost good assistant coach, inherited a winless UCF team and in year 2 went unbeaten and beat Auburn in a bowl game. Played under Tom Osborne and coached under Chip Kelly.
Really looking at it, any of of those guys could have and looking at their strong points, should have been successful at Nebraska. Point being, we have no idea who that right coach is and who will be successful here.
