New York Knicks fans have not heard much from Jeremy Lin since a knee surgery relegated him to the sideline this month. While he waits for his knee to be back at 100% again, Lin took the occasion to create a public service announcement on YouTube. The PSA was actually a video response to a invitation from students at Stuyvesant High School, a premier New York City public high school that requires examination for admission. At the video’s start, Lin pointed out that he won’t be able to visit the school at this time, though he would still share with them a few words of wisdom. Lin also affirmed his Christian faith, as well as brandished his playful side. In the meantime, the Knicks faces its first and biggest NBA Post Season rival yet, the Miami Heat, tomorrow afternoon.
