Just thinking about a way for Washington to get out of John Wall and for it to be worth it for the team taking him on. I think I found it:
Wall, Beal, 2019 Lottery Pick (unless Zion)
For
Cavs: poopoo platter of 2020 expiring contracts.
Wizards get cap clearing contracts, Cavs something out of their garbage assembly of assets, and are possibly a playoff team with a young core of lottery picks mixed with 2 all star caliber players. Wall of course a wild card potential 3rd star
