Hum, a coach who won some division titles but never a conference championship as most significant on your list, and a coach who won some division titles but never a conference championship at his current school as least significant on your list.
Just to toss some numbers out...
Solich: 58-19 at UNL (.753), 164-94 overall as HC (.636)
Pelini: 67-27 at UNL (.713), 94-49 overall as HC(.657)
Solich: 3 division titles in 6 seasons at UNL, 1 championship, 7 division titles in 20 seasons overall
Pelini: 4 division titles in 7 seasons at UNL, 0 championships, 4 division titles in 11 seasons overall
"Solich hasn't even won a MAC title. Not sure why so many people think he would have done any better here."
"Pelini hasn't even won a Missouri Valley title. Not sure why so many people think he would have done any better here."
I don't think it's implausible that Solich could have won at least a division title in 2004 or 2005. Maybe even a last-second championship game controversy in one of them...
Considering the hypothetical is "what if we would have won the conference with Pelini", that should be pretty obvious that the narrative would be different.
Comparing Solich's career - coming on the heels of one of the greatest runs in college football history - with Pelini's - coming off some of the worst season's we had in 60 years - doesn't exactly seem like an apples-to-apples comparison.
Solich has been at Ohio for 14 years and hasn't won a conference title. Pelini has been at Youngstown State for four years and made the National Championship game. Again, not exactly apples-to-apples.
