Heat- Get MPJ who could still be an all-star and kcp a rotation player. Also, getting Watson and Zeke are good for the future. getting two seconds this year and 2 first especially one in 2029 isn't bad either, and is good value.
Nuggets- Get a player that took his team to the finals 3 years ago and the conference finals a year ago. Pairing that with a back-to-back MVP would give them their best chance at a title.
