I think that misses the point. I don't think it has anything to be obsessed with either coach. I think the below point is the main concept.
Auburn has not shown consistency in being prepared for the season or for major games in quite some time. This season is a complete cluster gaggle in terms of readiness. Every season as of lately, we come out "trying to find ourselves". That is a scapegoat of an excuse if I have ever heard one. I expect some changes to be needed, but an entire rework of the offense is unacceptable. If I deliver a half-assed product to a client, which I don't; I expect to be chewed out and compared to other companies. Comparisons amongst competitors is natural and to be expected. You strive to grow and get better. If that doesn't happen, you get replaced/termed.
People focus on Saban and Kirby because their teams are an example of what Auburn fans are expecting. Consistency, planning, forecasting, and delivery. At a high level, Gus has shown an inability to be adaptable, forward thinking, and prepared. These are inexcusable with this many years under his belt. People will respond "Well, if you think you can do better..", but that is a logical fallacy. Coaching football isn't my specialty; so, I am no expert. You don't have to be an expert to see issues with project management though. This isn't a team new to being at a crossroad; this is a team that is consistently at a crossroad due to more planning. A team in flux with a fan base seeking as much direction and reassurance as the players appear to be seeking.
