Bridges isn't for sale. He might be part of a package for them to buy someone else, but they aren't looking to turn him into pieces this soon after trading two picks to get him. The Kings need Justin Jackson too much to move him without getting a better SF back. They do have Bjelica though, and I think he's significantly more gettable.
Josh Jackson is interesting. The Suns seem to be ready to move on, but I don't know if they'd be willing to trade him for parts. Like in next year's draft, I could see him going for teens pick. The Spurs could have such a pick then. But I doubt they can convince Phoenix that their pick is worth that now. MAYBE they'd be willing to go Anderson and Jackson for Mills, Gasol and the pick. But with them having Chandler on the roster already, I'm not too confident. Chandler and Jackson for Pau and picks? Maybe. It's at least salary-neutral. It's not even a little bad from the Spurs' perspective, because Jackson is a good prospect at a position of need, and the team avoids having to pay Gasol's guarantee and gets a chance at having another legit defensive center to mentor Poeltl. Just a hard-sell for a Phoenix team that already has an extra pick coming and prospects out the wahzoo.
