Why they do it:

76ers: Harden trade demand means they have to do something to salvage the situation or Embiid is looking at the exits. Getting two solid roleplayers AND a star back, this could be the best shot Philly has since the Butler Sixers

Clippers: Best case scenario, Harden, George, and Leonard stay healthy. A good/buyout center signs for the Vet Min. Westbrook is a great facilitator and the Clippers finally get their first title.

Worst case scenario, Harden's off the books next year and can be dealt in a sign and trade. Leonard and George get injured but have one year left on their contracts, and someone could be convinced to take one on a title long shot. Clippers reset their tax bill, and get ready for another shot at a stronger free agent class and convince someone to join them in Sunny LA

Blazers: Maxey is far better than what Heat and Nets could offer. Zubac has a ton of upside and can be dealt for assets, or kept to help see this Portland team through its first true rebuilding year. Harris can be dealt at the deadline or have his deal expired
