Roddy shut out in disappointing showing

LAS VEGAS -- These games aren't really about the score, but how the players play, particularly players a club is counting on when the real season starts. It's been an inconsistent summer league so far for Roddy Beaubois and it took a strange turn Thursday night in Game 4 of 5 -- an 88-82 loss to the Washington Wizards.

Beaubois went scoreless. His game went south early with four fouls in six minutes and five in nine (summer league affords 10 personal fouls). It never got any better. It was an awful performance especially considering the hype of playing against John Wall. Wall didn't shoot well (4-of-18), but he finished with 21 points and got to the free throw line 15 times (he made 13 -- the last four came as the Mavs fouled late as a last gasp). Wall added 10 assists -- he's averaged 9.0 a game so far this summer -- and seven rebounds.

Beaubois seemed to be out of sorts. He took just three shots and one of his three turnovers was a fumble of a pass out of bounds, a pure lack of concentration play. He had one assist and one rebound. Just an awful night knowing he was going up against the No. 1 overall pick. Beaubois played less than 16 minutes and he was effectively benched for most of the third quarter and the entire fourth quarter.

Meanwhile, Dominique Jones had a terrific game, finishing with 28 points, four rebounds and four assists. He attacked the rim hard and got to the free throw line 12 times (making 10). He's the only reason the Mavs were ever in this game, and why the final score was actually close when the Mavs trailed by double digits through most of the game. And it would be great to talk more about Jones, who has averaged 12.8 points in the three prior games, but...

This is supposed to be the Summer of Roddy and he has yet to dominate or even look anywhere close to ready to handling point-guard duties. To that end, it's good, he'll get the majority of his playing time next season at shooting guard.

Ian Mahinmi played in his first Summer League game with the Mavs since signing a contract earlier in the week. He finished with 11 points and seven rebounds, but was just 2-of-6 from the floor, including a missed dunk, and Washington's JaVale McGee was dominant with 18 points on 9-of-10 shooting, mostly dunks.

Omar Samhan continued to have a nice summer with 12 points and eight rebounds.
