Practice report: Full attendance

WALTHAM, Mass. -- The Boston Celtics had full attendance -- save for rehabbing Avery Bradley (shoulders) -- as the team got back to work Wednesday after taking two days off. Celtics coach Doc Rivers ran his team through a three-hour marathon session, but the team did only halfcourt work with a focus on execution. Some news and notes from the session:

* Rivers raved about the first full-team practice for newly acquired guard Leandro Barbosa.

"He’s been here for three or four days and the last two days we ran him through all the stuff. So he had a concept of what we’re running. He’s played against us for so long -- that helps as well. But he had a great practice."

Added Rajon Rondo, "[Barbosa] was very vocal today. He was the point guard. He moved [Jason Terry] to the side and I think they both liked that situation. JET's more of a scoring point guard and Barbosa set a lot of those guys up today in practice."

Barbosa said this week of practices leading up to opening day will be important for him getting comfortable in the system.

"I think those practices before we start the season are going to be great for me," he said. "Coaches have been helping me from an offensive standpoint and the defense. I’m a little familiar with what they do on offense and with the defense. I don’t think it will be a problem for me or take a long time to learn. I’ll be fine."

* Chris Wilcox, who has been sidelined with back issues since the first practice of the season, returned and went through a full session.

"It felt good," Wilcox said. "First day out there, it’s tough because you can’t really -- you've kind of got to feel out what’s going on. But I felt great out there today."

Later he added: "Man, big relief. Just sitting back there, working out every day on the sideline, seeing these guys go up and down, I wanted to be a part of it. They're out there grinding, getting ready for this year and I couldn’t be part of it, so today was a great challenge for me. I went out there, worked hard -- it’s the first day, so I didn’t expect too much, but I think I did well."

* Center Darko Milicic, who sat out the final four games of the exhibition season, deemed himself 100 percent after going through the practice. Milicic got a cortisone shot last week to alleviate discomfort in the ligaments around his sore right wrist, but said it's not an issue moving forward.

"It feels good," said Milicic. "I practiced today. It feels good."

Rivers said Milicic was "heavily taped, but he was fine."

* Rondo spent a minute talking about his improved free throw percentage during the preseason. Asked if he had a target percentage in mind for the 2012-13 season, he quipped, "One hundred. Subtract, like, 10. So 90 [percent]."

* Asked why he decided to return to Boston this season, Jeff Green directed the cameramen toward Rondo as he worked on a court nearby. "Turn the cameras right there. That guy right there. Rajon," Green said. "I wanted to play with him. He's the best point guard in the league. I mean, who doesn't want to play with a good point guard?

"Then you've got guys in the locker room like [Kevin Garnett], Paul Pierce, and now with the addition of [Jason Terry], and Brandon [Bass] coming back, and you've got Courtney [Lee]. I mean, we have a hell of a team. Who doesn't want to be a part of something special like this? We have a great opportunity to win a championship. I want to win, so this is a great chance for me to do that."
