That's the way the Celtics played against Miami on Sunday.
Now they need to do it the rest of the season.
"It's a no-point-guard system," Rivers said, noting that his second unit has been playing that way all season. "Now the entire team needs to do it. We have a lot of guards. We just don't have a lot of point guards."
Rivers said Courtney Lee, who has been averaging 7.2 points and 1.4 assists in 22 minutes, will start for now. Leandro Barbosa, Avery Bradley, Jeff Green and Jason Terry will also have the ball more without Rondo on the floor.
"I don't know if that's a role I'm going to have," said Barbosa, who backed up Steve Nash in Phoenix and is averaging 4.7 points and 1.2 rebounds in 11 minutes in his first season with the Celtics. "I'm not Rajon Rondo; I'm Leandro Barbosa. What I'm going to do is different for the team.
"I will do my best, but I'm not a point guard; I'm a shooting guard. I will do my best, but I'm not a Rajon Rondo."
There is also the possibility that general manager Danny Ainge would sign a player; former Celtic Keyon Dooling, who's working for the team in community relations, has been mentioned as a possibility. The Celtics, who were already languishing below .500, could also trade one of their stars and begin rebuilding.
"Danny has not brought up anything," Rivers said.
Rivers said he won't worry about Pierce being asked to do too much.
"I don't think Miami worries about running too much through LeBron (James)," he said. "I don't think the Lakers worry about running too much through Kobe (Bryant)."
