Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On the possibility of Russell Westbrook not signing a long-term contract with the Thunder: Westbrook has no reason to leave. He's an All-Star. He's winning. And he's got a great nucleus around him. The Thunder will pony up to keep him, so money won't be a factor. Not everybody wants to play in the big markets. Westbrook doesn't strike me as the kind of player who does. I doubt the Thunder, or its fans, have anything to worry about. I expect the two sides will iron out a long-term deal this summer. On Russell Westbrook saying he doesn't need a floater because he can just dunk on people: He's on record of saying he doesn't need a 3-point shot as well. Call it youthful cockiness. I think he sees his averages of 22, 8 and 5 and says, 'I must be doing something right.' But then every now and again I think he realizes he can't continue to let defenses back off him and not respect his perimeter shooting, or continue to wait for him to come charging down the lane to take a charge. On the Thunder's loss to Toronto Sunday: The Thunder didn't come to play. Plain and simple. When they did, they finally took the lead and showed they were the better team. But by then, the game was too close and it allowed anything to happen. And that's exactly what happened. Amir Johnson hit a game-winner. On Serge Ibaka's potential: Some days I think he's just going to be a great defensive player, a tremendous shot-blocker and rebounder. Then he'll throw out a drop step in the paint or a turnaround jumper and my eyes light up. He's got the tools, no doubt. He's just got to get more consistent and be able to do it when the defenses are focused on him. Those are his next challenges offensively, which is where most of his upside lies.
