What people rarely notice is Lin's defense. Not only did he have 5 steals, but he has rare talent to rattle the offensive player's timing and moving ergonomics by his own pacing. Even when he seemingly got beat by a step or so, he recovers quick and smart to make the shooter feel pressured, threatened and uncomfortable. His quick hands and steps also saved him many times on the brink of a turnover under pressure. I'd bet he learned Chinese martial art secretly.
That's probably why he is so fearless driving in the lanes and seems poised under highest level of competitive pressure way beyond his (NBA) age.
Case in point, rewind his game-clinching 3 in the Raptors game. You would see how he stayed rather calm and cool for about half minute after draining the shot before erupting like crazy or like most people would do immediately after the made shot. (Hey, Amare is annoying with his shouting 'and-1' before even getting off the shot!) That's rare and evidence of a great clutch player in the making.
