You get an upgrade with Artest over Ariza, I love Ariza and he is a great player but there is no doubting that Artest is a better player right now. Pau has been hurt since the start of the season, but he is still on the team. He will probably be back Thursday, their next game, with Big Drew as well. The fact that the Lakers lost to the Mavs doesn't both me right now because the Lakers were missing Pau, an all-star.
