A few I've noticed:
-Press conference after Md game. He looked weak, defeated, tired, etc. No energy. He looked like a man about to lose his job.
-little vocal support from Ron Wellman in the more recent past. This is very different then the end of last year Imo.
-players in the last few games looked as if they had given up, the energy felt depleted and gone.
-multiple news sources have come out saying he should be fired.
-the media coverage has lost almost all BuzzIN and/or BuzzWAIT..
-ads in the papers received tremendous exposure.
Those are just what I have felt. They might not be spot on, but that's my best shot at the 'little' things that I have noticed which point to him being fired.
Unfortunately, the insiders on here aren't quite so optimistic, so he'll probably be back somehow.
