I agree, throw out the DC years to compare them side by side, Pelini before 2003 and Scott before 2011. By the same timeline, Frost would have 2-3 years to go before getting his coordinator shot. That's by the same timeline, of course: Bo was a rising star through the rankings, and came on high recommendation (I forget who - was it Kiffin?). The same really cannot be said for Frost.
I don't know how you can look at the two situations as remotely comparable houseofspears. First of all, it's misleading. Scott was a graduate assistant at Nebraska in 2002, but that's it. Same with Bo (not grad assistant in 1992 according to wiki), but the difference is three years later Bo is rising through the ranks in the 49ers organization, and three years later Scott still has just one year of GA under his belt and is not coaching. Frost has coached for six years now including this one. Six years! He's had four years as a positions coach and two of those were LBs coach with UNI. Maybe someone can comment on his "co-DC" status that knows more about the situation. But we are talking about him for OC, mind.
Scott has exactly two years as a positions coach at the FBS level and those same two years are the only ones where he has coached anything on the offensive side of the ball. So let's hold the horses before we automatically consider him a chip off the Chip Kelly block. (Oh, come on, that was
funny... 
)
Look at Bo's career. Eight years as positions coach in the NFL. Worked with some top minds and he really was soaking up their knowledge, and came highly recommended as a bright prospect in the profession. The same could be true of Frost, eventually, but I don't think it is now, and looking at resumes won't change any of that. When he comes highly recommended, then it would be something to talk about.
As it stands, Scott has six years of ground at the very least to cover, so even looking at the resume it is not even remotely comparable. But as I said, more important than that are recomendations and those who know more about the guy's specific abilities as a coach. And I know nothing about that. If Scott is a rising star, I am sure he will find his place. If he really is a rising star, I am sure we would get him, too, given his apparent willingness. We have a former player coaching here who are not even rising stars or have much potential in the profession, so I think one that is a stud would get snatched up quickly.
Frankly it's very unclear the path Frost's career is going to take right now, IMO. In ten years, he could be a DC somewhere, or maybe he's a head coaching candidate here, I don't know. Or maybe he is still coaching some position on offense or defense at some school.
