That's the case if you're willing to trust Artest at his word — or, more specifically, his Twitter account. The Lakers' new forward expressed a desire to prove something to his former team:
"Houston did me dirty. I can't wait til next year when we go to Houston. I'm not shooting. All defense. Somebody getting locked da —- up"
Artest won't have to wait long, as the Lakers fly to Houston for just their third game of the season on Nov. 4.
