Ya know it's kind of ironic. Frost talks about how they did things back in the day under Osborne a lot. Personally I love the stories and insight and I love listening to him talk about it. What they didn't have to deal with back in the day was social media. It was mostly local newspapers and rumor mill, from what I assume. They didn't have to worry about as much noise because there wasn't anywhere for the noise to go really. Local reporters could voice opinions, and as long as games were won, no one cares. Now? Shit, you got noise and articles from everywhere under the sun.
Kind of a deeper thought, but I wonder if he really truly knew what he was walking back into, from all aspects, given the success that he had at the time at UCF and Oregon, and just that he hadn't been back in an official or important role since like 2000 as a grad assistant. In hindsight, I don't think he really knew all angles, and I think it's a lot of what you said of just riding the success high for as long as he had.
FWIW, I'm perfectly okay with him figuring things out as a Power 5 HC as we go here and dealing with the highs and the lows. Some people aren't, that's fine. I've seen shitty football basically since shortly after I can remember, what else is new? I still hope he's my generation's Tom Osborne who also had to find his way a little, but in simpler times.
