By now, every single person on the planet has heard about Jeremy Lin. The hype has just been amazing, and a lot of it is well deserved. He's proving to the world that he can run a basketball team successfully in the NBA.
Lin is especially adept at running the pick and roll. That bodes well for Amar'e Stoudemire, who made a career for himself by running the same play with Steve Nash, the master of the pick and roll.
Regardless of how tremendously talented a player is on offense, it's harder to defend a two-man play than it is to defend an isolation play. The pick and roll is a deadly offensive weapon. With the New York Knicks having the perfect pieces (Lin and Stoudemire) to run the play, it's a must that they make it their top option.
That means that Anthony is going to have to accept being the third option.
Anthony has established himself as one of the best pure scorers in the NBA. He's been a franchise player for many years. He's also been the first option on offense since high school.
The "demotion" might not do well for his ego. However, winning an NBA championship would.
The 6'8" forward can still be a deadly threat as the third option. He simply needs to wait for Lin and Stoudemire to initiate the offense. If they can't get things going, then the ball can be rotated to Anthony. He would then have free reigns to bail the team out before the shot clock expires.
Offensively, the Knicks would be hard pressed to do better than having those options. Surround those three with outside shooters and defenders, and long suffering Knicks fan can finally have an NBA championship.
They just need Anthony to make the sacrifice.
