To be fair, we do pile on every time he has an opinion of what the team should do, we talk about Spo being great so he can't say anything. Does that mean none of us can ever say what the Lakers or Warriors should do if it's different than what the coach does?
No, but how often do we actually do that or call them a shit coach.
Just like when he cries about the refs, he does it far more than anyone else (not even close) so he gets shit for it.
