Yeah, Jeremy Lin has been good for the Knicks while they have had some injury worries. The only problem is that he is a shoot-first style point guard. When the Knicks regain their full squad, he is going to have to change the way he plays because two All-Star are coming back - they are on big money and pretty much control the team and who takes what shots. Carmelo Anthony is one of the best pure scorers in the league and Amare Stoudemire is an absolute beast in the low post.
Jeremy Lin has been very good for the last ten games, but teams will begin to adapt to him and defend better. Unfortunately for him, basketball experts reckon he has problems with his hands on dribble penetration (to the basket) and the game above, he had 38 points, 10 rebounds and, I think, 14 turnovers - which is ridiculously high.
However, he was undrafted and the Knicks took a chance on him and it has paid off. He is on NBA minimum salary, but this should all change for next season. He probably has another couple of years as a backup point guard before he takes control of a team.
