I would do:
Napier and 2018 second rounder for Rodney Hood - Jazz will not want to pay him in the Summer as Mitchell is a better and younger prospect, and they badly need a point guard that can shoot.
Harkless for Courtney Lee - despite good game last night Harkless IMO doesn't want to be here, and New York is his preferred destination. Lee has had a decent season and he has similar contract only shorter.
CJ for Saric, Johnson, 2018 Philadelphia 1st round pick, 2018 Lakers pick - Philadelphia will want to compete for playoffs this year and if they decide that they won't get LeBron or George in the off-season, CJ is exactly what they need. We get two decent picks and a combo forward with great playmaking ability.
Then say we have no. 8-10 from Lakers, and two picks around no. 13-20 - our own and Philadelphia's. That could even allow us to move into top 5 but most likely it would also allow us to get one of Miles Bridges and Kevin Knox and another two young talents. That's a great rebuild.
Here's what I would change to get something like 5-6 firsts:
-Still do Napier and a 2nd for Hood
-3 team deal:
BOS Gets: Davis, MIN/LAL 2nd (via POR)
NYK Gets: Harkless
POR Gets: Noah, Thomas (TPE), 2018 BOS 1st, 2018 NYK 1st
*NYK sheds $14M in unplayable contracts for free agency and adds Harkless. BOS trades their late first for a future early 2nd a big they need, using the injury exception from Hayward.
- Trade McCollum, Vonleh to PHI for Saric, Bayless, Anderson, Johnson, 2018 PHI 1st, 2018 LAL 1st (Top 5 Protected - 2019 SAC 1st backup)
*More likely for PHI to take this trade, as they would trade out contracts that would allow them to have more cap space for PG or LBJ next off-season.
- Trade Aminu to CLE for 2018 CLE 1st, Shumpert.
*CLE could use a backup SF, and adds another guy that could guard Draymond/Durant. Would get Frye's minutes.
So we'd have this rotation to finish:
Lillard / Bayless / Baldwin
Anderson / Connaughton / Layman
Hood / Turner / Thomas
Collins / Saric / Swanigan
Nurkic / Johnson / Leonard / Noah
And would have the following picks:
LAL (8th?)
POR (9th?)
PHI (13th?)
NYK (16th?)
CLE (27th?)
BOS (28th?)
Let's say we package 8, 13, and 27 (or 16) for 4. A team like PHX would likely do this, trading down to 8 expecting Sexton or Young to be there (Young and Booker would be like Steph and Klay). They would also have either Bamba or Jackson Jr. there so they'd be safe and would add two picks. That could be a combo of Sexton+Walker, or Young+Carter Jr., etc.
We'd likely have Michael Porter available there at 4. (Doncic, Ayton, and Bagley go top 3, if not, draft one of them).
At 9 we could go with Miles Bridges
At 16 we could go with Lonnie Walker
I'd attach 28 to Bayless or Thomas to shed salary (BKN?), get a trade exception, and cut the other one.
Let go of Anderson, Johnson, Thomas, Connaughton, and Layman.
Lillard / Baldwin /
Hood / Walker /
Porter / Bridges / Turner
Collins / Saric / Swanigan
Nurkic / Leonard / Noah
An under-24 core of: Nurk, Collins, Porter, Bridges, Saric, Walker, and Baldwin to go along with Lillard (28) and Hood (26).
