NOP: Ian Mahinmi and Kelly Oubre
OUT: Solomon Hill, Wesley Johnson, and New Orleans 2019 First Round Draft Pick*
Why for New Orleans? Upgrade their back-up center position marginally and get massively needed wing-depth (and bird-rights) through Kelly Oubre.
Why not for New Orleans? Take on three million dollars more in salary next season and potentially lose a first.
MIN: John Wall, Austin Rivers, Solomon Hill, Wesley Johnson, New Orleans 2019 First Round Draft Pick*, Washington's 2019 First Round Draft Pick**
OUT: Jimmy Butler, Jeff Teague, and Gorgui Dieng
Why for Minnesota? Gain an all-star player in John Wall, consolidating future salary into him, whilst gaining two firsts.
Why not for Minnesota?

The trade kicker is actually a deal-breaker. Minnesota is taking on so much long-term salary with this trade. Makes shoddy spacing in the starting line-up worse.
WAS: Jimmy Butler, Jeff Teague, and Gorgui Dieng
OUT: John Wall, Austin Rivers, Ian Mahinmi, Kelly Oubre, and Washington's 2019 First Round Draft Pick**
Why for Washington? Massively improve and balance the roster, whilst dumping a potential albatross. Amusingly enough, they barely take on salary, and actually save a substantial amount overall.
Jeff Teague / (Sign a scrub, can't be worse than Austin?)
Bradley Beal / Tomáš Satoranský / Jordan McRae
Jimmy Butler / Jeff Green / Troy Brown Jr.
Otto Porter / Markieff Morris / Jason Smith
Dwight Howard / Gorgui Dieng / Thomas Bryant
Why not for Washington? Salary-wise and roster-wise it works out well, but should the team fall apart, and not meet expectations, giving up John Wall and the pick would sting in the short-term.
