The New Orleans Times-Picayune (Jimmy Smith) reports: For all those NBA teams — the Hornets included — who were hoping for yet another comeback by veteran forward P.J. Brown, there’s no good news in the new year. Brown said Wednesday he is officially retired. “My career ended June 17,” Brown said of the day he became a world champion when the Boston Celtics defeated the Los Angeles Lakers for the 2008 NBA title. Brown had left a voice message to The Times-Picayune to that effect nearly five months ago, on Aug. 7, but would never use the “R” word.
