10. Klay Thompson's defense.
As a long-range gunner with barely a season of NBA experience, Thompson just seems like a guy who should be a poor defender. But the more I watch him, the more he looks like a really solid defender. He moves around well, with a good understanding of rotations and the general team concept. He's a willing worker with good balance; he can close out hard on shooters while keeping his feet steady enough to prevent a blow-by drive. Thompson has a chance to be a really, really good all-around player.
