The Lakers were beaten down in the second half of Game 2 tonight against the Dallas Mavericks, scoring only 32 points and falling into a 2-0 hole in the best-of-7 series. Games 3 and 4 are Friday and Sunday in Dallas and the Lakers have a lot of work to do if they hope to get back into the series and save their chances at a three-peat. They might have to play without Ron Artest, who could be suspended for whacking Jose Barea in the head in the final minute. Andrew Bynum said the Lakers have “trust issues.” They sure seemed at the breaking point after Dallas pounded them into submission.
