No, not all hate him. I despise his thought process, crazy or not. But, he is entitled to his opinions and if it is due to mental health issues, not a good stance to take against the elderly. If he does get PI's, they will find dirt and then others will try to play who did the nastier deed. It will get uglier and in the end, the NBA will be the ones to feel the impact financially.
With enough investigation anyone can be exposed. If Sterling pays the right price there will be people lining up left and right disclosing the improper actions of other persons of influence in the NBA.
