Isaiah Thomas tied his career high with 37 points for the Boston Celtics at New Orleans on Monday night. In New York, Harrison Barnes registered his fourth straight 20-point game for the Dallas Mavericks. "I think we're at a time where as a team each person has to look at individually what they can do," Barnes, who won a ring with the Golden State Warriors last season, said after the Mavs, again playing without Dirk Nowitzki, lost 93-77 to the Knicks.
