Not surprise that Lin is doing well at all. Since summer league in his rookie year, he showed that he can play. This kid is a very hard worker with a very high IQ. Those qualities are essentials for a good PG. He also has good size for his position.
Obviously he won't be able to substain these high octane stats over a long period, but he will develop into a nice player. Was super surprised that the Warriors would waive him at only $500k salary. Heck, with such a large Chinese population in the bay area, it would've been easy for them to make much more than that just with some promotion to the community there.
