I hope you are right, but I think he is gone.
Right now, he is still a feel good story. And overall, he is still thought of very favorably around the state. Yet, he knows 1-9 in playoff series is not good and he is close to being turned on by all if playoff clunkers continue. He also knows it is going to be much tougher even getting to playoffs over next couple years with Brewers and worse SP.
Leaving now allows him to go elsewhere for big bucks METS, get whatever resources and FA he wants, and chase WS yearly.
Then, he STILL would be welcomed back to manage Milwaukee years later.
