Here, the Cavs decided to rebalance the roster around Mitchell and Mobley. Assuming Donovan does not demand a trade, they would be wise to try and maximize his effectiveness, while also choosing to put Mobley in his more natural spot at the 5. Surrounding them with shooters who can either defend and play make with help the offense tremendously, and they should still be very solid defensively. Simmons could potentially give you something off the bench, and worst case he is a huge expiring contract that would either help them make future moves at the deadline or help clear up their books in the future.
The Nets get a young point guard in Garland to pair with Bridges as it seems clear they do not really want to rebuild and seem intent on keeping Mikal.
The Thunder get a real 5 who can help them fix their biggest issues, rebounding and size. Allen will bring a great interior presence and can pair nicely with Chet to make a terrifying defensive front court.
The Jazz decide to move Lauri and not extend him, and get back a nice collection of assets in return to help them truly bottom out and rebuild.
