ShamSports has a brilliant if terrifying idea, one which he doesn't really endorse but presents nonetheless:

At the center, it's not a "risk vs. safety" decision. It's "immediate risk vs. future risk." I would err on the side of future risk, given the way the CBA winds blow and questions regarding Landry's knees. But if the Kings have no other major plans for this summer, it wouldn't be the worst idea the try and lock in Landry through his peak. Some very interesting algebra in there.
