They renounce KO, stick Yabu overseas, trade Rozier and Jackson into someone's cap space, and get rid of the rest not named below. Works under the cap:
Max FA 30,300,000
Horford, Al 27,734,405
Bradley, Avery 8,808,989
Top Pick at 120% of Scale 7,026,240
Crowder, Jae 6,796,117
Thomas, Isaiah 6,261,395
Brown, Jaylen 4,956,480
Smart, Marcus 4,538,020
Zizic 1,645,200
Nader 815,615
Min Player 815,615
Min Player 815,615
Total 100,513,691
Doubt they can get a max FA though and then it becomes a matter of who they can get in FA and who does the saved money help keep? Doubt there's a trade, but who knows with Danny.
Finally, why anyone would want to get rid of Crowder and his cheap contract is beyond me.
