Salaries work just fine.

Clippers get back a 28 year old star that will still be in his prime as the contract wraps up. He could be the third option on offense, allowing him to be an excellent off-ball shooter and playmaker.

This is for sure a short sighted move and obviously comes with an extension. The thought process here is Paul George fits better with Ant for the next 3 years and provides a better second on-ball creator. Also, defense likely doesn't take much of a hit as George is still a solid defender.
