After a rough game versus the Heat and relatively quiet All-Star Break, Jeremy Lin came back in full force leading the Knicks to a 120-103 victory over the lowly Cavs.  Linsanity was back to his old ways with 19 points and 13 assists in yet another virtuoso performance at the PG position.  He also showcased his toughness after suffering a bloody nose at the hands of Omri Casspi and taking another hard hit from Tristan Thompson.   Lin-sanity brushed off the physicality and kept going to the hoop, demonstrating yet again why he is force to be reckoned with.
