The only time I have heard it mentioned was by a few posters who say that Walters must be unhappy with the roster management decisions of O’Shea (presumably because they are unhappy with it, so every one in the organization must be as well) and it has caused a rift. And that the rift extends to Miller, who needs to sit OSH down and give him a talking to. Serious projection from some disgruntled posters, IMO.
But if any of the “insiders” know differently, by all means let’s hear it. It would be very surprising to me though. Why would Walters be mad that the roster he has built has been very successfully deployed by OSH at a level of excellence not seen consistently in these parts for some 60 years. And is Miller really upset with his coach for rostering a team that has gotten them their 3rd straight home West Final playoff game, led to a surge in season tickets and sellouts, and big profits?
Things have not been this rosy in Bomberland in my lifetime, except for those unhappy folks lamenting the inevitable decline and worrying about the other shoe dropping instead of embracing the joyful ride, and the mild criticisms take on a life of their own, and then it manifests itself into these types of rumours of a hidden bad blood that will topple the house of cards. Just my take.
