Well, I understand the spirit of your question, but I think it could also be asked: What do you think Scott Frost thinks about Frank Solich and Bo Pelini. Frost is a lot of things, including a fairly consistent word master when it comes to talking about other people. He's slipped up here and there, but his m.o. seems to be a bit of a politician when it comes to what he says.
I'm guessing that his thinking is a lot more complementary of Pelini than Solich because Bo seemed to energize on toughness, crass as he could be about it. Solich uncorked a good second career at Ohio, but as said before, that's a program in a conference that elite coaches grow then move on to first tier schools/conference.
Which brings us to Frost's credentials. But that's a different thread.
