I'll bet Goose could come in here and run this flexbone offense (as a coordinator) just fine. Remember "the Goose is loose"? I don't know Godsey at all personally, but he gives me obvious impression that he is, as we say in Maine, "wicked smaaht". He has a breadth of offensive experience that most coaches wouldn't. My point for saying this, is not conjecture about his future status here, but rather that I don't think his NFL pedigree or experience will have poisened the well at all from the GT perspective.
I may be way off the mark here, but I have the impression that Goose could show up to the GT football offices, spend a week in the film room with pizza boxes and empty bottles of mountain dew piling up around him, and emerge needing a shave, but ready to run this offense. We may never choose to court him and he may never want to come back, but, in any case, the end result will not be influenced by his inability to do it.
Personally, I am married to this flex-bone system, especially in the context of its suitability to our beloved institute. I said "I DO" several seasons ago. I know that CPJ will not be here for ever. If I were AD, the next guy who comes in as HC at GT would have to be committed to carrying that torch. We would be crazy to change. So, as much as I like Godsey, if he were for changing the offensive game plan, then I say "no thanks". We are all enjoying a historic run of offense at GT over the last several years that really has no peer. Dismantling what we have built smacks of insanity. When you look at the FEI stats etc we compiled from last season and their position in the history of the stat itself, then consider the wide gap that existed between us and the second / third place teams, whose vaunted offenses are revered by the rest of CFB fans everywhere, it should start to sink in.
