Napear keeps talking about D. Jordan in FA. He's only 30, which for a center isn't old. Could be a good stop-gap for the next three years. He can still play D and rebound and his free throw shooting isn't a problem anymore. If the Kings do go after him in FA, it's a sign they believe Bagley and Giles can be good enough with their outside shooting to spread the floor for Fox. If you think about it, WCS certainly didn't spread the floor, so if you substitute Jordan you get another guy who doesn't spread the floor, but is a much better rebounder and rim protector.
If not Jordan, Whiteside would be solid too
