Over at USA Today, Steven Ruiz ranked all of the NFL head coaches -- and he lumped all of the first-year head coaches together, 31-28 -- with Mike Mularkey of the Tennessee Titans being number 32. That cop-out is pretty common in head coaching rankings: no one knows quite how a first-year head coach will do, so they just refuse to make a ruling.
That leaves us with an actual thought experiment: where would Dirk Koetter rank among the current head coaches? He has a long track record of success as an offensive coordinator, though he's never quite gotten stratospheric there.
