I actually wouldn't mind adding Lamelo, IF the plan is to also get a starting center somehow. It doesn't even have to be a superstar or expensive big, just a reasonable decent/solid starting center who can also allow Queta to flourish as a backup big.
Lamelo
White
Jaylen
Tatum
Solid Center
Bench: 4 of Minott/Hugo/Queta/Walsh/Hauser/Pritchard
BOS - Ball, Landale
MEM - Hugo
CHA - Simons, Hauser, 26 1st, 28 1st, 27 swap, 29 swap
That seems like a reasonable trade for all 3 teams. Landale isn't going to do much, but he can spread the floor, rebound, won't get in the way or make mistakes. Be a solid 5th starter type player. Real downside is he is expiring and on a minimum so he'd have to be re-signed this summer to really help in the future.
