The AP reports: Finally healthy after two seasons virtually lost to knee injuries, Gilbert Arenas had 29 points and nine assists as the Wizards took an early lead over the revamped Dallas Mavericks and never let go on their way to a 102-91 victory Tuesday night… Arenas shot 10 of 21 and made 8-of-9 free throws for more points than he had all of last season… The assists included several nifty passes that set up Brendan Haywood for dunks. He also helped set up reserves Andray Blatche for 20 points and Randy Foye for 19 in his first game with the Wizards. Caron Butler added 16 points, with injured forward Antawn Jamison watching from the bench. He’s likely to miss the first eight to 13 games because of a shoulder injury… But the Mavericks fell into the old habit of trying to ride a big night by Dirk Nowitzki. He scored 34 points, but was only 10 of 25. He was 12 of 13 from the foul line—all in the first half.
