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 the Thunder needs to do to beat Dallas: Defend the perimeter to limit the 3-point shooters. Win the rebounding game to prevent second-chance opportunities. Use its defense to get out and run for easy buckets. And limit turnovers. On his prediction for Thunder-Mavericks: Haven't quite figured it out yet. Two things are in play, though. On one hand, the Thunder could take advantage of Dallas' long layoff and ride its wave of momentum and steal Game 1 on the road much like Memphis did to the Thunder. On the other hand, the Thunder will have to adjust extremely quickly to its third different style of play in these playoffs. OKC didn't fare so well at that going from Denver to Memphis. So those will be the two biggest factors in a win right now. A third is Dallas is perhaps overconfident. We'll see. Right now, I'm leaning toward the Thunder. On which Thunder player could guard Dallas' Dirk Nowitzki the best: Kevin Durant. He's long enough, athletic enough and smart enough. I have my doubts about how much Brooks will rely on KD. He probably won't want to tire him out or get him in foul trouble. But this could be a turning point for KD defensively. On which Dallas Maverick will guard Kevin Durant: Shawn Marion has a better shot at containing Durant than anyone on the Thunder has at containing Dirk. But in general, I see your point. It's going to be a nice chess match. On whether Serge Ibaka will have a "bounce back" series: Wouldn't mind seeing Serge at the 5 on Chandler and KD at the 4 against Dirk for major minutes. Maybe throw Harden and Cook at there at the 2 and 3 with Russ at the 1 so you have floor spacing in addition to a more athletic lineup. But Serge will start on Dirk. On Dallas' zone defense and how the Thunder will handle it: Daequan Cook wasn't playing as well as he has been of late when the Mavs threw the zone at them in the regular season. Cook might not have been playing at all. So I think his presence should help. If the Mavs do go zone, I'd love to see Brooks throw Nate Robinson, James Harden and Daequan Cook on the floor and dare them to stay in it. On the best lineup for the Thunder vs. Dallas: I like KD, Russ, Harden, Collison and Serge in some situations and KD, Russ, Harden, Serge and Perk in others. I don't know if the numbers back up my belief, but to me those are by far the most effective lineups.
