I agree with everything in your first paragraph. My only bit of contention is that in the year 2017, I think the promotional aspects of the job are absolutely necessary for the vast majority of programs. Nick Saban, and the like, can get away with the "bunker mentality" because of their absurd success/track record/built-in enthusiasm within a given fanbase. But Saban is more the exception than the model. Fleck seems over-the-top but I think he is merely just ahead of the curve. As attention spans continue to shrink and entertainment options expand, I think the constant promoting of one's program within a community will become nearly as valued as the film room or game plan.
As we move forward, college coaches will become more similar to politicians and less like hard-nose military generals/tacticians . Just my opinion/prediction. Very intelligent guys like Coach Claeys will likely be relegated to coordinator positions because they simply don't have the skill-set/desire to attempt to insert themselves into every aspect of a local community.
