The Oklahoman's Oklahoma City Thunder beat writer Darnell Mayberry answered questions from readers in today's Power Lunch chat. Read the entire chat recap here. Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On what he thinks OKC forward Serge Ibaka will average next season: A double-double. He's become much more confident in his offensive game, and he's always been a willing rebounder. If he stays on the court without picking up silly fouls, something in the neighborhood of 12 and 10 isn't out of the question. But his main focus probably should be improving his man defense. On how the Thunder would fare with a "hard" salary cap: They're set up well for it already. But if the cap comes in on the low side and you absolutely had to make sacrifices, KD, Westbrook and Ibaka would be the three I'd hold onto the tightest. Harden would be a close fourth behind Ibaka. On if Thunder star Kevin Durant would participate in a "barnstorming" tour while the lockout is on: Knowing him, I wouldn't be surprised if he's signed up. But he is with another agency than the guys who are talking about it. Maybe that doesn't matter at the end of the day. But one other thing to consider is KD has to be exhausted already. He's had camps in Chicago, OKC and Austin, He's in China right now doing a Nike tour. And he worked out for a week or so in L.A. prior to all of that. Dude needs a break. On whether Russell Westbrook could average 10 assists next season with James Harden starting at shooting guard: No. The total is more likely to go down, actually. And perhaps it should. Harden is a better playmaker. If he does indeed start next season, he should have the ball in his hands a good amount to make things easy and cut out some of that foolish one-on-one stuff. Russ averaged 8.2 assists last year. With a full year of leeway and a green light to attack, I see that number going down. Besides, only three players averaged 10-plus assists last year: Nash, Rondo and D-Will. CP came 0.2 assists shy. That's a hard thing to do.
