Hawks save ~9 mill by going from Capella to Looney and waiving Biertans. They turn the starting Center Keys to Okongue or Alex Sarr.
Hornets would waive Paul and also clear up an additional 5 mill of cap space after getting rid of Biertans gauranteed contract, and all it cost them to do so is moving down a little in the 2nd round.
The Warriors are probably gonna waive CP3, but this allows them utilyze 14 mill of CP3s contract to upgrade from Looney to Capella. They also move up in this years draft and get a 15.7 mill TPE which would allow them some flexibility to add to their roster.
