WALTHAM — Doc Rivers  knows the Bobcats have had the number of the last two times they’ve met, including a 26-point blowout on Tuesday night in Charlotte.
So don’t expect the Celtics  to look beyond the lowly Bobcats on Saturday night in advance of their showdown with the Heat Monday night at TD Garden.
“No matter what our excuses are, they beat us two games,” Rivers said. “One game they beat us soundly and one game we kinda sputtered down the stretch. And no matter what you say to them, they’ve beat us twice. They are going to have great confidence against us. When you beat a team, they don’t care about the excuses, they know they beat you and that makes them a better team the next time they play you. When they beat you again, that makes them even a better team the next time you play them. So [Saturday] they are going to play great, and we have to expect that and we have to try to beat them playing great.”
The two players expected to lead the Celtics Saturday night in their revenge match are Paul Pierce  and Kevin Garnett , who have been the talk of the town this week after both reached scoring milestones on Wednesday and Garnett explained afterward how close the two were growing up.
Why is this story so special?
“That’s only because they’re old as hell,” Rivers answered with hearty laugh. “The only way you can reach those milestones together is you have to hang around a lonnnnng time. It is cool. I was joking but it does seem like every night one of those two does pass some kind of record. I think now we create some sort of new record to pass but it is awesome. They have that picture together, it’s a neat picture when they were 15.”
Meanwhile, Rivers was asked about how Rajon Rondo  might fit into Celtics plans down the road and if he’s thought of changing his offense when Rondo is ready to return at the start of next season. Rivers said he’ll let Celtics GM Danny Ainge worry about most of that.
“I don’t think about it much,” Rivers said. “Again, you know how I am, when guys go down, there’s nothing we can do about it. I have given next year zero thought, I’m hoping Danny will do a better job of that than me — that’s his job. But I don’t think about that much at all.”
