Being a Head Coach already, it doesn't seem likely to take a step backwards even if it is a step up in rank. College Coaches get shots at the NFL just like Coordinators do.
Well, In Groh's case, he had a HC job in the NFL and quit after 1 year. Supposedly not liking the pressure.
That being the case, I wouldn't think he'd be looking to return to the HC ranks in the NFL, which
could lend a bit of credibility to an interest at the coordinator level. Meaning that (getting a 'shot' or not) he would not be interested in being an NFL HC again.
However, I think it's far more likely that he simply prefers College and would not want to return to the NFL in any capacity.
