It depends on your definition of home run. A home run for me is simply a guy who actually has collegiate OC experience and has demonstrated competence in that field. We are looking to take the step from the bottom rung of the ladder towards the middle rung. Maybe at some point in our program's future, we'll be looking to step up to finding elite assistants, but that's not what we need right now, and that's not attainable anyway.
And, yes, absolutely needs to avoid NFL flameouts. Really, should avoid NFL guys altogether. It simply hasn't worked. Running a pro style offense does not necessitate having an OC who has coached in the NFL. Few college OCs who run pro style offenses very successfully have any connection to the NFL. Beamer seems to be locked in on this notion that to have a pro style offense you've got to have an OC with NFL experience.
