Jeff Green, Nenad Krstic join Celtics

LOS ANGELES -- Jeff Green and Nenad Krstic, acquired in Thursday's trade deadline shocker that sent Kendrick Perkins and Nate Robinson to Oklahoma City, took the floor with their new Celtics teammates for the first time during Boston's morning shootaround Saturday on the campus of UCLA in Westwood.

Green and Krstic logged some extra time with the coaching staff after the session, but beyond the crash course in Boston's philosophies, both expressed excitement about joining a championship-caliber squad.

"It's an honor," said Green. "There's a lot of history behind the name that's on this jersey. I'm proud to be a Celtic. I'm coming here to do the best I can, try to help this team out and win a championship."

Added Krstic: "It's going to be a great experience for me. I can learn so much from these guys. Hopefully we'll win a championship this year and I can go back to Serbia with a ring."

After passing their physicals Friday, the duo met with the coaching staff to start going over Boston's playbook. Even as they get up to speed, coach Doc Rivers said he'll toss Krstic into the starting lineup during Saturday's game against the Los Angeles Clippers, while Green will settle into his role off the bench.

"It's going to take some time, obviously, but we'll throw them in," said Rivers. "Jeff will take longer in some ways because he has to learn two positions, the 3 and the 4. We're going to throw them in there, throw them in the fire. Nenad will start tonight and hopefully he can figure it out on the fly. We don't have a lot of time."

Green said the pair were well-received by their new teammates and is fully aware that chemistry may be the most important factor moving forward.

"They accepted me well," said Green. "I can already tell the tight bond, these are guys you go to battle with. It's important to have that relationship with each other and they welcomed me and Nenad with open arms."

Green laughed when asked about choosing jersey No. 8; Krstic will wear No. 4. Combined with Chris Johnson wearing No. 86 after being fetched from the NBA Development League on a 10-day contract Thursday, the new Celtics have all inherited former Celtics' numbers (Robinson wore No. 4, Erden wore No. 86 and Marquis Daniels had No. 8).

"Man, so many numbers are retired in Celtics' history," joked Green. "There wasn't a lot of numbers to chose from. Eight is a great number, I'll try to represent it well."
