The Oklahoman's Oklahoma City Thunder and NBA beat writer John Rohde 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 the OKC Thunder's offseason and potential free agent signings: It is very possible the Thunder retains all 15 players on the roster, which would mean re-signing Nazr Mohammed and Daequan Cook. It's also possible [GM Sam Presti] could deal Nate Robinson, Byron Mullens and not re-sign Nazr and/or Cook. The whole free agent thing is goofy because there is no CBA and no one can do anything until one is in place. The most intriguing free agent to me might be Carl Landry, but Nawlins presumably will hang onto him any way possible. On what fans should expect out of Kendrick Perkins next season: Given his price tag, it had better be quite a bit more offensively. It was good to hear Perk say he wasn't too pleased with himself, but the guy was 75 percent healthy, tops. If he's healthy, I still think a double-double is within reach. Truthfully, I don't think that's too much to ask, either. Said he's going to come back at 265 pounds, which is 20 pounds lighter. On Game 1 of the NBA Finals tonight: Heat is unbeaten at home, but this is the Mavs' best shot at winning. They can shock Miami with how good they are. The Heat is more talented at three positions, but Dallas is smarter. I'm the only person I know picking the Mavs, though. On rookie center Cole Aldrich: From what I've seen, I believe Aldrich has passed Mullens. Aldrich consistently handles Mullens in 3-on-3 or 4-on-4 pregame get-togethers. Will Aldrich start in place of Perkins? Not even close. But he and Mohammed could be solid backup centers by committee.
