Let me first say that I did not watch the Detroit game so I cannot say who Doc is most upset with, though I can tell he is disgusted with the way this team plays in the 1st quarter of games. And I am too.
Having said that: I think we are making a too much of this. Sometimes a coach just has to lay into his players, and that's basically what Doc did (at the same time criticizing himself, ever the players' coach).
It wasn't that long ago that Doc said he liked his team and thought they were getting better. He wanted to see consistency...day-in, day-out. Obviously that did not happen in the New Orleans or Detroit games. The Chicago game was a tough fought game they should have won.
I don't take anything away from this talk about people not taking losing seriously enough. Who cares about attitudes after losses? What matters is the attitude on the court, the level of play.
I also don't take anything away from Doc's threats that "guys have to go." Doc is not the GM. Danny is. Danny will definitely trade the whole freaking roster if this team doesn't act and play like a contender. We don't need Doc handing out threats to make this a reality.
I am glad Doc is p---ed, but if it doesn't make the team play better than all he has done is shown they don't respond to him anymore. That is what I am most worried about.
