Rajon Rondo  will become a restricted free agent next summer if the Celtics do not sign him to a contract extension by October. On Monday he was tight-lipped when it came to business, suggesting any questions could be answered by his agent, Bill Duffy. ‘I don’t know. I don’t know. I don’t really think about it,’ Rondo said. ‘I try to just focus on camp. If it’s going to happen, it’s going to happen. If not, I’ll play it out.’ He reiterated that he will play wherever he is wanted and that his main focus is getting another ring. … Rondo, 23, gained 11 pounds this summer ‘because I’m growing up.’ He trained with a new weight-lifting routine, ate three meals a day, and cut fast food from his diet. He also plans on hiring a chef.
Celtics president of basketball operations Danny Ainge would like to keep Rondo around as the team’s point guard for the next 10 years and has had early talks with his agent about future plans. He has not, however, had discussions with Ray Allen  about his expiring contract and will not address that issue publicly. … Ainge has high expectations for the upcoming season. He believes the offseason moves and returning talent will be successful. ‘We’ve added some great depth, our young players are improving, and Rondo, Perk and Glen Davis , they made great strides last year and I think they’re even going to better this year as their games are maturing. I think that Rasheed [Wallace ] and Marquis [Daniels ] give us two more starters, proven starters, that are coming off the bench for us that should give us a lot of depth,’ Ainge said.
Paul Pierce  is making his confidence in the Celtics perfectly clear. He believes they are the best team in the league when healthy, pointing out they were on a record-breaking pace last season prior to injuries. ‘People are going to say what they want to say about my comments or whatever, but I have total confidence in this ball club,’ he said. … Even though Doc Rivers  would prefer to cut back on the veterans’ minutes this season, Pierce refuses to sacrifice playing time for wins. ‘I’m not willing to lose nothing. Next question. I don’t understand that, losing. No.’ … He compared seeing Kevin Garnett back on the court for 5-on-5 drills as a ‘breath of fresh air.’
Ray Allen kicked off media day with some humor while waiting for Pierce to join him and Garnett at the podium. Allen grabbed the microphone to locate his teammate: ‘Paul Pierce. Paul Pierce. Your food is ready.’ … The Celtics’ window of opportunity to win a championship has been mentioned since they acquired veterans Allen and Garnett. Allen, though, is more focused on the here-and-now than two or three years down the road. ‘We don’t look at a window. We’re not looking past this year. We can’t look past this year,’ he said. … Allen is not concerned with adding a player like Rasheed Wallace to the mix. He pointed out many of them have known Wallace since high school and the Celtics have already learned each other’s game.
Kendrick Perkins  is heading into training camp 15 pounds lighter than last season and is down to 270 pounds, his lightest total in three years. Perkins did not have a weight-loss regimen but rather trimmed down during his workouts. … His shoulder, which he has dislocated in the past, feels better than it has ‘in a while.’ Perkins noted he is not worried about suffering another injury and is feeling strong. … The big man has been impressed by Wallace on and off the court. Even though he did not know what to expect at first ‘ ‘I didn’t know. I was just waiting to see. It was kind of like scary for a moment,’ he said ‘ Perkins praised Wallace’s versatile game and pointed out he is a great addition to the locker room.
