George Hill
I was very impressed with what I saw out of Hill. Defensively is where it all begins for the rookie point guard. He can pressure the ball the length of the court and he uses his combination of quickness and length to disrupt ballhandlers.
Perhaps even more impressive is his ability to help defensively -- whether it be play the passing lane or switch off onto a bigman. Hill isn't as advanced offensively but his outside jumper looks much better than it did in summer league. I'd still like to see him finish at the rim with more authority and up his level of aggressiveness but overall Hill has surpassed expectations so far in preseason. However, with news that Hill injured his thumb and even possibly tore ligaments, that could be a major blow to both Hill's progression and the Spurs' backcourt.
