Logic:
Cavs are in title contention mode, but are facing the impacts of the second apron. Instead of tearing it down, they flip Garland for Jrue Holiday, which will save them millions, while also keeping them in the hunt for a title. They also pick up some high value 1sts to help them build out their roster in future years.
The Blazers, looking to take a step forward into playoff contention, consolidate their young assets and picks for an all-star point guard in Garland, and a high-impact 3-and-D wing in Ellis. These players ages and roles align well with a young up-and-coming core of Avdija, Camara, and Clingan.
The Kings, looking on the brink of a rebuild, trade one of their high-impact role players for a high-risk, high reward gamble in Sharpe.
