OKC trades with NOP
OKC - Steven Adams, Eric Bledsoe, Pick 10 NO - Kemba Walker
This gets NO another star to put alongside Zion and Ingram while getting off of Adams and Bledsoe. OKC gets a top 10 pick here. OKC can also offer a 2nd rounder if need be to get it done.
OKC trades with SAC
OKC - Pick 9, Marvin Bagley SAC - Pick 16, Pick 18, Pick 34
This gets Bagley out of SAC while allowing OKC to consolidate two firsts and move up. Since most analysts believe the talent pool is similar from 8-20, the Bagley and 2nd rounder help to even out the value a bit. SAC can then address a ton of holes on their roster. They could also get Adams from OKC (via NO) if they won't bring Holmes back.
These moves would allow OKC to get Barnes/Kuminga at 6 and potentially Bouknight and Sengun at 9 and 10 if they keep those picks.
These picks could also be used to move up into the top 3 if those teams are interested in trading down.
