Not to mention in the grand scheme of things it wouldn't matter anyways as the majority of teams would still be on the cap. It would benefit the owner in saving luxury tax than it would the player.Because it’s disrespectful to the union. If a superstar of Curry caliber takes a pay cut owners will use that against other superstars. The Union would never allow that.
I also would argue against owners using it against other superstars you'd almost always find a team willing to overpay.
