I've really enjoyed what Lin has done to revitalize the Knicks during that run and the NBA for that matter. He's a great kid and wish more players in the NBA had his attitude.
That being said, with D'Antoni gone his game may not translate as well.
Since we're not trading Melo, we need to do everthing in our power to pair him with Dwight Howard. That means including Lin, Shumpert, Fields with Amare & Tyson.
Melo & Howard would look pretty good in a Phil Jackson Triangle offense.
