His next year is not guaranteed. If the Jazz cut him (or more likely buy him out so he can go back to Europe), they're on the hook for his contract this year and nothing more. On the flip side, they can trade him and Diaw at the deadline, giving another team $10 million in cap space next year if a valuable acquisition for the offseason came available. I'm thinking Rudy Gay in particular. Jazz could throw some picks at Sacramento, match the salaries, rent him for the last part of the season and have his Zbird rights if they want to retain him in the offseason.
