You consolidate your excess wing players ,and a frp you don't really need and get for a rim protecting big that you desperately need.

New Starting Lineup:

PG: Amen Thompson

SG: Jalen Green

SF: Tari Eason

PF: Jabari Smith Jr.

C: Jarred Allen

New Bench Lineup:

PG: KPJ (hopefully trade him for an actual backup PG)

SG: Josh Christopher

SF: Cam Whitmore

PF: Usman Garuba

C: Alpheran Sengun

I know it's probs not perfect for Cleveland, but they can move Mobley to the centre now he has had time to build up to NBA level. Plus it solves their problem at the wing position so it might work out still.
