It is also evident that nobody was going to trade for him anyway.
Well, this part is the issue and now officially dead.
The Wizards could've always traded him to the Suns for example. Wall for Anderson and a protected future 1st would've gotten the Wizards out of that horrendous contract and given them a future asset too.
The Suns have been looking for a PG and since they don't play in a major market adding a "star" is tough. Enter Wall, who may not play like a star, but adding him to a young core of Booker, Ayton, Bridges, Jackson, and a likely top 5 pick this summer would be enticing.
