I wasn't born back then, so I can't speak on what happened to Dr. J or Tiny Archibald. I just know in today's NBA nobody is forcing trades to get out of a contract. The bylaws don't allow it. You can't force a team to terminate your current contract for a new contract for more money. Even if a team wanted to do it, you're not allowed to do it.
Luka Doncic is still on his rookie contract making 10 million a year, he's been the best player on the Mavs since his rookie year, yet he's the 5th highest paid player on the Mavericks right now. You think both he and the Mavericks wouldn't want to terminate that rookie contract and go ahead and pay him 40 or 50 million a year? He's worth that and more, he's an international superstar, but a contract is a contract, you have to wait until it's over to renegotiate.
