WALTHAM — The buzzword around the Celtics  these days is “versatility.” In Jason Terry , Courtney Lee  and especially Jeff Green , coach Doc Rivers  has a number of different lineup combinations he can use, and he plans to test them all. Rivers pointed to Rajon Rondo , who was getting stretched out behind the media scrum. “He’ll be very happy.”
Their last practice before departing for Istanbul was devoted entirely to using small lineups, although small is a relative term. The C’s believe that the 6-foot-9 Green can force matchups whether he’s at the three or the four and there’s even a thought of playing him and Paul Pierce  together with two traditional bigs.
“We put it in [Sunday] but we didn’t work on it,” Rivers said. “Today we’re going to have almost exclusively have small lineups on the floor so that will be fun. This is the first year we’ve ever really worked on it and we’re going to work on it so we can do it every game.”
Green is the key because of his length and athleticism. Last season, Rivers used Mickael Pietrus  as a smaller small forward with Pierce playing the four. That lineup was almost born out of desperation as a counter to Miami using LeBron James  as the second big around a lineup of perimeter shooters.Rivers doesn’t just want to matchup, he wants to attack and he sees Green as a force in the open court.
“He’s the main guy when you talk about small lineups,” Rondo said. “He played the four at Oklahoma City, he stretched the floor with his shooting. We can get a lot of bigs on the floor as well. He can go from the four to the three. Defensively, he can check one through four, I believe. We expect a lot out of Jeff but he’s fine with that pressure.”
A key to making the smaller lineups work is also coming up with an offense that won’t stall when Rondo is off the court — a frequent occurrence last season. With no traditional backup point guard on the roster and Avery Bradley  out for a few months, that task may fall to Terry.
“He’s a better ballhandler,” Rivers said. “I knew he could score of the dribble but he’s really a natural at the point. That surprised me. We have no choice right now with Avery out. We’re trying to create an offense where it’s not a point guard dominated offense, unless Rondo’s on the floor.”
