One definition of insanity is doing the same thing over and over and expecting a different result.
We should not treat traditions as sacred cows. FWIW, I don't think that candy-striped warmups and Martha the Mop Lady are the problem. But that we're so hesitant to accept change is -- and the devotion to nameless jerseys is symbolic of that.
We don't just need "a competent coach." We need more than that. We need a paradigm shift -- a new coach will be necessary to have that. But hiring a new coaching staff without allowing more fundamental change to occur will likely (IMO) just lead to another disappointment and the belief that the problem is that we still just haven't found the right guy.
IMO - I disagree. The problems with this team stem from the coach and his insistence on running a 2000's style NBA offence and his coaching staff's lack of ability to recruit a balanced team. The stadium, facilities, uniforms and fan support are not the problem.
