IMO Cousins doesn't respect the organization he works for, and represents. There are few former Kings' players, old timers, present or past that have Cousins respect. The organization has never shown they can all get on the same page, and build a winner, never mind a champion. He acts like a spoiled child because his (parent) organization is lacking. At this point he has no one in the Kings organization to shame him.
If DeMarcus Cousins were traded to the Lakers, San Antonio, Miami, and yes...the Celtics, he would be presented with the opportunity to view multiple banners, meet the legends daily that contributed to those banners, and hopefully would mentor him into acting like a champion.
The fact is DeMarcus needs to get out of Sacramento before he looks up and he's Derrick Coleman.
