Reasoning:

Nuggets - Peyton Watson has been balling recently and has increased his value, Denver does not have the cap space to sign him for what he’s worth. In this package they get Rui who can play Johnsons role and is expiring so the can use the money to keep Watson.

Lakers - Johnson is better version of Rui with improved defense. Terence man can help the bench defensively as well.

Nets - get off manns contract and get pick swap
