WALTHAM — The dunk happened sometime today between 1 and 2:30 p.m. when the Celtics  had their practice closed off to the media, but it did happen.
Doc Rivers  worked the Celtics  hard Monday, one day after a preseason game with the Nets , and one day before a back-to-back set with New Jersey and then Toronto  in Hartford. During the session, Kevin Garnett  went up for a lob and brought it home.
“Kevin was great,” Rivers said. “I don’t think he came out today. He’s getting stronger and stronger. The only thing left, today, he caught a lob and dunked it. It was an amazing dunk and everyone was like, ‘Whoa, we haven’t seen that.’ He’s not as explosive yet, but it will come. You can see it. When he did it he yelled out, ‘Oh I can do it.’ That was good to see.”
“I think Doc wants me to grow wings and fly,” Garnett said. “I tell him just to be patient. The wings are coming.”
The wings, and everything else, are coming into focus for the Celtics as they reach roughly the midway point of training camp. The starting five is back and healthy and the reserves have shown enough in the preseason games that the bench seems far more settled than it has in the past.
Still, there remains work to be done incorporating the new players ‘ Rasheed Wallace  and Marquis Daniels  particularly ‘ into the offensive and defensive systems as well as learning the little things about each other that only come with time and reps.
“Even though everyone has a high IQ when it comes to basketball, we still have chemistry [things to work on],” Garnett said. “Where ‘Sheed likes to have the ball, where Marquis likes isolation and everybody understanding everybody’s game. It’s not a big thing, but it’s something that you have to give a certain amount of attention to. The new guys have to learn our schemes and understand terminology.”
There’s no question the Celtics are feeling good about where they are with the season-opener at Cleveland looming in a little more than two weeks. A big part of that is fact that the players came into camp in basketball shape.
“Every guy on our team has come to camp in better shape than they were last year,” Rivers said. “Eddie [House] came to camp in phenomenal shape. Kevin, conditioning-wise, is probably not where he was last year because he spent half the summer not being able to work out. But everyone else: Paul [Pierce]  is in great shape, [Glen Davis ] is in great shape. A lot of that is that we lost and no one likes that feeling. You want to do something about it.”
NOTES: Part of the reason that Rivers worked the team so extensively Monday is that he plans to rest the veterans in at least one of the next two games. Look for the coach to use that time to begin working on some rotation patterns. Rivers said that he is set on the first four off the bench ‘ House, Daniels, Wallace and Davis ‘ and then the rest will sort itself out depending on matchups.
Pierce turns 32 Tuesday (look for a story by colleague Jess Camerato that day) and while the captain was not in a mood to reminisce, Garnett offered his thoughts on his teammate. “Paul makes things easier,” Garnett said. “I’m not going to lie about that. He not only makes things easier, but simpler. Offensively, things get simplified, plus a lot of things he and I don’t need to talk. We have a bond and a chemistry that’s unspoken.”
Pierce on rookie Lester Hudson , who is three months older than six-year veteran Kendrick Perkins : “He’s a 25-year-old rookie. How many of those do you have? He plays mature. He came in and he understands the game a little better than your average 19- or 20-year-old rookie. That’s good.”
