Why the Knicks do this: Josh hart is a great player, but his fit with the team in the playoffs this year was questionable, mainly with his ability to hit the 3. The Knicks let go of Hart, but gain a true stretch 5, where now the Knicks can play a 2 big lineup with any combination of their 3 bigs. This will let Kat play the 4 more.
Why the Spurs do this: Hart seems like a great fit for the spurs, adding defense and rebounding to help Vic preserve his body. Hart if only 30 so he could be with the spurs for 3-4 years after this.
Why the bulls do this: They are bad. They need draft capital.
