According to several reports, Tyus Jones, Daniel Gafford, and Kyle Kuzma are all potentially available to be traded. If the price is right.
The Wizards seemingly enter any negotiations around Gafford or Kuzma from a position of strength as there's really no rush to trade either. That being said, if they get the right deal then it may be the right time to trade either or both players while their value is currently high and the market seems to be titled in the favor of sellers right now.
Tyus Jones, given his expiring contract, seems like the most likely player to get traded.
