And I understand that. If it was a perfect science, people would be picking the same style of HC each year, but they don't. You're pointing out the ones that didn't work but you could easily point to a McVay or a Shanahan or a number of other guys and say it has worked. Same would hold true for the CEO types - some have worked, and some have not.
To be clear, I have no real problems with Weaver. His players love him as a leader. I guess my biggest question is if you're going to swap out Harbaugh for someone who is going to operate in a similar manner, why did you move on from Harbaugh at all? The real "success" is kind of predicated on the coordinators around him in this scenario.
