Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On Russell Westbrook going into "hero mode" against Cleveland: I wasn't impressed with how he scored in the third quarter yesterday. Everybody else seemed to be. But to me, it was classic hero mode. He was just putting his head down and looking for his own offense without considering his teammates. The reason no one can have a problem with it is because he was incredibly successful. Had he been called for a charge or two, or missed some shots it would have been ugly. But he didn't, so it's all good. The bottom line is I agree with you. When Westbrook is getting everybody involved, spreading the ball around and other players are cutting for easy baskets, the offense is much, much better than it is when one player tries to carry the load. On Kendrick Perkins' impact on the Thunder even without playing: It's given [Nazr] Mohammed a chance to get some rhythm and timing down with his new teammates. And I think he's been able to see what [coach Scott] Brooks wants and how the team would like to play without being thrown into the mix immediately. That might help him pick up things faster once he is out there. On what the Thunder will need in the 2012 NBA Draft: I still think they could use another shooter. There isn't much playing time to be had these days. But a shooter and a backup on the wing would be my target. On whether James Harden will start over Thabo Sefolosha: It doesn't look like it's going to happen this year. I would think that the start of next season would be a good time to insert him into the first five. It makes no sense to make the change after 64 games and make everyone get adjusted to a completely different unit. Plus, right now he's extremely good off the bench and is helping to balance the scoring between the first unit and the reserves. I'd be sort of shocked, though, if that move isn't made next season.
