Linsanity is just about over in New York. The Knicks plan to cut ties with Jeremy Lin on Tuesday night, according to a person briefed on the decision, ending a brief, spectacular and now bittersweet love affair between the 23-year-old point guard and his adoring fan base. Lin will play next season for the Houston Rockets, who signed him to a three-year, $25.1 million offer sheet that the Knicks have elected not to match.
