You guys are really underestimating the practicality of undersized players defending in the post. Take a look at Chuck Hayes. What Blair needs to do in the offseason is watch a lot of film of the better small big men in the league, and how they defend. He's not capable of being the primary help defender - his height and mobility limits his ability to switch away from his man to help out on penetration. Therefore, he is limited to defending the opposition's best big, and he can do that in the paint. With his butt, long arms, strength and low center of gravity, he can make life really hard on a post scorer...If he can do that, he will be a starter level player.
