Sunday night when Stephon Marbury's father started having chest pains during the Knicks game, one of Stephon's kin folks instructed them not to tell Stephon. "Don't tell Steph," a relative said, according to a Knicks official. "Let him play." Sources said a relative told Knicks officials Don Marbury had a history of these types of episodes. Stephon, the second youngest of Don Marbury's seven children, didn't need that kind of distraction right now, the relative said. He played the entire game not knowing his father had died. A Knicks official said Marbury did not complain about being left in the dark about his dad's demise.
