Bullying and playground politics just isn't the right way to think about this.
Kyrie, e.g., put the economic pressure on himself. Nike sells shoes. They don't want to pay him anymore because he can't sell shoes nearly as well now, and might impact their ability to sell shoes long-term. Regarding the Nets and NBA, Kyrie's many million dollar contract isn't exactly for playing basketball. It's for his ability to get lots and lots of people to want to watch basketball. When he pissed off a lot of people he doesn't do that very well, and his value as a basketball player drops.
