Lakers take a shot at bringing in a big to play next to AD. They basically only lose Vandy for him. They also clear enough space to sign 2 minimum deals.
Knicks have 2 empty roster spots assuming they keep Shamet. It adds depth and brings a defensive playmaker.
Wizards take a shot on a 2nd year player giving up a end of bench player (who I think plays a solid role for New York)
