New input: Article: February4, 2012 saw the take-off of a new rising NBA star- Jeremy Lin. Among professional basketball players, Jeremy Lin's background is not typical. He graduated from Harvard University, which sends few players to the NBA, and he is the only Chinese-American NBA player. But when you watch him on the court, there is no doubt that he belongs there. He moves with speed and grace that demonstrate years of faithful practice, which is fueled by a love for basketball. Lin's enjoyment to basketball actually began in Taiwan. When Lin's father moved to U.S., his interest in the sport only grew and he passed on this love of basketball to his son, introducing him to the game at the age of five. The young Lin spent much of his youth playing basketball for fun. In high school, Lin dreamed of playing in the NBA. When he applied for college, he was not offered a single sports scholarship. However, after his admission to Harvard ,he was offered a place on its college basketball team. During Lin's time at Harvard, his basketball career began to speed up. He scored 1,482 points, making him one of the highest scorers in Ivy League history. When he graduated, no professional teams offered Lin a contract, but he was invited to play in the NBA Summer League. He played well and ended up eagerly signing a contract with the Golden State Warriors. At first, playing in professional games filled Lin with excitement.
