The most unlikely to do this sort of trade is the thunder, as they are already the 1 seed and have a guaranteed lottery pick (High one if this trade is done), so this trade is quite farfetched and would be only in the circumstances that they feel the pick isn't worth more than a quality backup big on a good contract and 2 future firsts that can hold value.
Clippers: PG: Sheppard, Mann, Paul, INJURED(VanVleet) SG: Ivey, Bogdanovic, Beal SF: Jones Jr, Holland, PF: Collins, Harris, Batum C: Zubac, Lopez, Niederhauser
Get back their pick this draft to tank for a one of the top 3 guys
Move away from their retirement home identity
Rockets: PG: Harden, Holiday SG: Thompson, Okogie, Christie SF: Durant, FInney Smith PF: Smith Jr, Eason, Green C: Sengun, Adams
Reunite with Harden and officially put their hat in as the best team in the league
Amen is the perfect complimentary piece to Harden and this team would be very scary
Pistons: PG: Cunningham, Sasser SG: Robinson, Levert, Lanier SF: Thompson, Green, Dieng PF: Leonard, Klintman C: Duren, Stewart, Reed
Hope to get a solid version (possibly happier version) of Kawhi, who on a good day can be a top 10 - 15 guy beside Cade.
Based on their targets such as AD, and Lauri Markkanen, it seems they are happy to ship Jaden Ivey and Ron Holland. Again, a hypothetical.
