I stated he knows how to coach, just is not doing well in handling during game situations. His expectations for the new players to be perfect on defense is over the top. He is embarrassing himself and his players with the way he is acting on the sidelines. He has gotten mad at his asst. coaches at times also which just looks bad. He has to be in better control of his emotions in order to coach his players better.
I agree I have noticed he seems to be way more emotional this year during games. I don't think it inspires confidence in the team, and as a fan it worries me what all is going on.
