"Mike is clearly out of it... Time for both parties to move on"
You see signs that confirm that MDA is on the way out. I don't agree that your signs settle anything. Mike continues to have an opportunity to mold a very talented bunch of guys into a winning basketball team. At the end of the season, Amare and Melo will likely have the leverage to either bring Mike back, or have Dolan let him go.
Mike continues to have a fair chance to build a winning team. If he succeeds, and his superstars feel they are getting closer to winning a championship, he is likely to stay. If Melo and Amare are not on board with MDA, then that is a sign that his being let go is nearby. Reading that Mike's lack of enthusiasm after a tough win against the Bobcats proves he is resigned to leaving the Knicks, could simply mean that he was exhausted, couldn't it.
