Here is my idea
Boston trades TA, Scali, JR, 1st, trade exception and Cash
for
Sessions, Gomes, and Jawai (trade exception)
Boston adds two strong bench players at reasonable contracts for the next few seasons.
Minn gets another 1st to help rebuild around Flynn and Jefferson
Minn save money this year (about 1.2 in less salaries and tax plus 1.4 million with the TE and tax)
Minn saves money next year with Scali, JR and TA off the books (though I would not be surprised if TA starting there earns another small contract)
The money sent can be used to buyout Scali, who can then return to Boston when the Celtics waive Jawia.
