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...
