I personally wouldn't trade Fox, but the speculation from Amick that the way the Brown termination was handled might push Fox further out the door, is concerning. If you are going to deal with a Fox trade, what about:
Rockets receive: Fox, Alex Len
Rockets give: Jabari Smith Jr., Reed Sheppard, Jock Londale or Steven Adams (filler), 2025 FRP (Suns), 2027 FRP (Nets)
Why for Rockets: They get Fox, the best player in the deal, and I think it immediately makes them a contender. Their top 7 would be Fox, Green, Amen, Eason, Sengun, Brooks, and Van Vleet, and would still have guys like Whitmore, Tate, and Holiday. They have to give up a lot, but given the price for Mikel Bridges, it seems like Smith, Sheppard, and two picks is fair value. Note that this could also work with Eason or Amen instead of Smith, so long as the filler was Adams, not Londale. So there is some wiggle room on the particulars
Nets receive: Huerter, Reed Sheppard, 2027 FRP (their old pick, back from Houston)
Nets give: Cam Johnson
Why: The Nets get the FRP and young player they want for Cam. Added benefit is that the FRP is their own pick back. Huerter makes the salaries work and could be flipped for assets.
Kings receive: Jabari Smith Jr., Cam Johnson, Steven Adams or Jock Londale (filler), 2025 FRP (Suns)
Kings give: Fox and Len
Why: If you are going to lose Fox, this sets you up to be competitive in the short run while also having some nice assets in the future. You would presumably convey the Hawks pick this year, but still have a 2025 pick from the trade. You would then control all future picks, and would have a nice and competitive core:
Sabonis/Adams or Londale
Smith Jr/Lyles
Keegan/Cam Johnson
Demar/Keon
Monk/Carter
The forward depth would be young and dynamic, with Keegan, Smith, and Cam offering a lot of interchanging options, and Lyles as a tough guy to get some minutes. You would have a banger behind Domas. The guards would be a fun rotation, and you would have the opportunity to groom the two spot for Keon or Carter in the future.
If you HAVE to trade Fox, it might be the best way to do it.
