4-way deal:
Cleveland gets George.
Indiana gets Boston 2018, Memphis 2019, Clippers 2019
New Orleans gets Love, Philly 2017, Brooklyn 2018, Lakers 2018 (SAC 2019).
Boston gets Anthony Davis.
(Trade made in July since we otherwise fail the Stepian rule).
I don't believe that a lineup of IT, Bradley, Crowder, Davis, Horford could beat Golden State.
It could beat Cleveland as they are currently assembled - not convinced it could beat Cleveland with Lebron AND George. That's a lot of firepower to try and stop, and a lot of defense to try and score against. A Lebron + George combo would be deadly at the end of games.
We would need another piece. If we traded for Davis
and managed to sign Hayward as well, then I think a rotation of Thomas, Hayward, Crowder, Davis, Horford could compete with any team in the NBA.
