I feel like I need to clarify the steps:
1) Three-way trade with Denver, Sacramento, and Boston
Boston receives: Isaiah Thomas, future Denver 2nd
Denver receives: Randolph, Bogdonavic, Yabu
Sacramento receives: Denver's trade exemptions, Hayward, Bird
2) Celtics restructure Kyrie's contract, able to add up to 10 million more (10 million in cap space after the trade) to his contract and extra years to his contract, depending on what the rules are.
3. Celtics trade Baynes, Brown, Morris, Rozier, and Williams plus picks for Davis.
Celtics are left with Irving-Smart-Tatum-Horford-Davis and Thomas-Ojeleye-Theis-Wanamaker-buyouts on the bench.
The big question would be whether or not a restructured rose-rule contract is still considered a rose-rule contract.
