It All Makes Sense Now
This post feels a bit like rubbing salt in an open wound, but I just can't resist.
When Mike Singletary was fired from the San Francisco 49ers, he got himself a new gig in Minnesota, and described the position as exactly what he'd held with the Niners before his fateful promotion - linebackers coach and Assistant Head Coach. In San Francisco, that latter position seems largely to have been as a motivational speaker, but undoubtedly there was more. And though it's quite a fall from head coach to positional coach, meaning Singletary still has never been a coordinator, the "Assistant Head Coach" eases the blunt.
When interviewed, this is what Singletary said:
[Mike] Singletary confirmed in an interview with Chicago radio station ESPN 1000 that he will become an assistant to Vikings coach Leslie Frazier, with whom he played in Chicago.
"I will be in Minnesota with Les," Singletary said. "I will be a linebackers coach/assistant head coach."
Now ... here's how the Minnesota Vikings list Singletary on their website:

Yeah, that says Special Assistant TO Head Coach. Kind of a major difference. (Also, there's another guy named Dennis Polian whose entire job is 'Assistant to Head Coach.' For what that's worth.)
Calling one the "Assistant Head Coach" when in fact, you are an Assistant to the Head Coach sounds familiar. Sort of hilariously so. And, everything begins to make sense now -- Mike Singletary is Dwight Schrute:
I WANT WINNERS!
It's just incredible that he didn't succeed as a head coach. Wow.
