Hmm, I see your point, but the situation is a little different. I see dumb decisions at work from the perspective of an insider and as a "professional" in my field. I associate threads like this more closely with the "Occupy Wall Street" movement, where the protestors have limited knowledge of what they are protesting.
Assessing the GRob example, GRob did some things right, but his biggest problem was not having a plan. His offensive and defensive schemes were non-existent or constantly changing, as was his staff. This created confusion with his team and led to his undoing.
It is quite possible to be successful employing less than optimal plans as long as there is a consistent approach to the task and a buy-in by those working towards the goal. Conversely, plenty of brilliant plans have failed because there wasn't a proper conveyance of the overall vision or there was a lack of consistent effort, while plenty of "blunter" ideas have succeeded because of the application of persistence and teamwork.
I can't help but chuckle at posts on here that claim that the offense has to be "this way" or "that way" to be successful because it works at State U. There are examples of pro-style offenses that are successful in HS, so why is it too difficult for a college team to run? Do I want to see SU get more production from it's offense? Of course, but keep in mind that every play is designed to go for 6 (other than a kneel-down).
