Has any head coach ever had it as good as Zimmer?

Someone recently asked me in the comment section underneath one of the more recent case for firing Zimmer articles why I hated Minnesota Vikings head coach Mike Zimmer. First of all, I don’t hate Zimmer. That’d be like hating a beige paint job. It isn’t great, nor is it awful, it’s just run of the mill.

But, when pondering how to respond to that comment it occurred the me the very best term that sums up my feelings about the Zimmer era is: return on investment.

What have the Vikings brass received in terms of success in exchange for what they’ve invested in and for Zimmer?

First up, what investments?

You know, just the most any one franchise has invested or given a head coach in NFL history?…
