The most significant part of the return the Washington Wizards got in the Bradley Beal trade is salary cap relief. Instead of paying Beal an average of over $50 million annually for the next four years, the Wizards received Chris Paul and Landry Shamet, whose contracts are non-guaranteed after this season.
Kyle Kuzma and Kristaps Porzingis have player options for next season. Porzingis is likely to pick up the option, and Kuzma is a prime sign & trade candidate. There is a decent chance that neither of these players will be a Wizard past next season.
