The meteoric rise of New York Knicks Point guard, Jeremy Lin, an improbable Harvard graduate Chinese-American NBA basketball star who became an improbable media darling despite a Time Warner Cable contract dispute with the MSG Network, prompting New Yorkers to illegally stream games in the winter of 2012.
