Danny goes over the top for many calls that aren't that bad and is surprised when no one listens after actual bad calls. He also makes it weirdly personal compared to most other animated coaches. So the refs just don't listen to him any more. You can see it in real time... they do not care what he has to say. Overtly ignore him.
What we're seeing is a result of Hurley's actions. When you treat people like crap, you aren't going to get the benefit of the doubt when you plead for a review or something. He's not going to see a change in how refs react to him after 1 or 2 blow out games keeping his cool like some people think. It isn't about the chip or how many games we've won. They simply don't like Hurley. Some more than others, but it's clear as day.
That being said, I hate the zebras and thrive on the animosity. I'm all for it. Love it, in fact. Our coach is a psycho and I wouldn't have it any other way. I just think it's funny when folks act surprised the ref won't talk to our coach or we get some questionable calls against hs.
