You definitely need to pay more attention to what is going on ...
Basically what makes him a nutcase base on the CURRENT situation. I just want to understand your reasoning...so that I may agree or disagree.
At the moment, I don't think his action warrant him a nutcase. His respond while repeatedly stating the same thing over "do what the coach wants"...it's not that far off what Carl Landry stated when he was frustrated. Taking it to the coach office is what player should do when they're frustrated IMO...and it's up the coach to show guidance (if they have any) and buy into the game. What happened in there, we don't know, but obviously DMC yelled something about "if you think I'm a cancer then trade him". I don't see anything wrong with that either. (all quotes are not exact )
Unless I'm missing something big that Cousins did than my bad but that's what I got from the situation without all the speculations.
