I think the most glaring was that we never would have thought we have Lin and Novak. They were buried on the bench. Novak owe a lot to Lin for making him shine. Almost nobody knew who he was until Lin started passing to him and discovered what a sharpshooter he is. We almost never thought they existed.
It truly was a perfect storm. Jared, Fields and Shump were also playing better during Linsanity, like they really were playing like they really care about winning. Motivation was in the air and everyone, even other teams fans were enjoying watching the Knicks.
