Frank Solich was a good head football coach but IMHO he isn't quite worthy of election to the CFB HoF. Nothing on his coaching resume unequivocally suggests he is among the all-time greats of his profession.
Nebraska:
6 seasons as head coach but only 1 conference championship (1999). Only agents trying to bolster their client's negotiating stance get excited about division titles.
11-13 record vs. AP Top 25 opponents. The 24 games are as follows: 9 home, 10 road and 5 neutral site games.
2-3 record in bowl games.
Only 1 win vs. Top 25 opponent on the road (27-24 OT win at #23 Notre Dame -- I was there!!). Note this doesn't include neutral site games (i.e., conference championship games & bowl games), so the 66-17 Alamo Bowl win over Northwestern isn't counted.
Good: 2 wins as a lower ranked team vs. a higher ranked opponent.
Bad: 5 losses as a higher ranked team vs. a lower ranked opponent.
Ugly: 4 losses as a ranked team vs. an unranked opponent.
Ohio U:
16 seasons as head coach without a conference championship. My previous comment regarding division championships (above) applies here. Record-wise, that's not the mark of a hall of fame coach. Yes, Ohio U football was a joke much of the time before he arrived so he deserves much credit for building the program and raising expectations. But we're not talking about Northwestern level futility before Randy Walker & Gary Barnett arrived in Evanston and stunned the college football world.
True, Solich set the MAC record for football games won. However, IMO that accomplishment is in large part because past great coaches in the conference had departed for other programs long before they could have set any such record. The MAC has historically been the starting point for up and coming coaches including Saban, Meyer, Hayes, Parseghian, Schembechler, Kelly, Kill, Pinkel, etc. Once they proved themselves, they were usually off to bigger and better programs. Solich just happened to end his coaching career in Athens rather than start there.
I hope Solich enjoys his retirement years and is (finally) able to do things he wasn't able to while he was a college football coach.
