I don't get the logic behind that.

The STs coach becomes the interim HC? Has that ever happened before?

He has to have been the 3rd or 4th choice.
I'll bet that GW and McGuiness declined. Maybe there is just too much loyalty to Fisher either in reality or in Demoff or Kroenke's eyes.

Other than enthusiasm and a dad who was a HC, this has to be a desperation pick. Not that it really matters. What matters is not wins, but that the Rams fans have been given 2 things: 1) knowledge that Kroenke is paying attention, and 2) hope.
