HBO has released the trailer for the upcoming "Linsanity" documentary "38 at the Garden," which chronicles former NBA star Jeremy Lin's spectacular run as he led the New York Knicks to a winning streak. The documentary will look into how Lin, 34, took the NBA — and the world — by storm after scoring 38 points against the Los Angeles Lakers at Madison Garden during the NBA 2011-12 season on Feb. 10, 2012, resulting in the start of the cultural phenomenon known as "Linsanity."
