LOS ANGELES — Rasheed Wallace  will start for the injured Kendrick Perkins  in Game 7 of the NBA finals . Celtics  coach Doc Rivers  made the announcement about an hour before the game.
“He’s old. I figured I’d play the oldest guys,” Rivers joked of the 35-year-old Wallace before giving a serious explanation. “I just think it’s a good combination with Kevin [Garnett ] because of the size, with Bynum’s size. I just think it’s a better fit for us.
“It also may give [Rajon] Rondo  a chance to get loose early because of the spacing on the floor.”
The decision to go with a taller lineup against Andrew Bynum  and Pau Gasol  also means that Glen Davis  will come off the bench. Otherwise, Rivers doesn’t expect many other changes with the loss of Perkins to two torn ligaments in his right knee in Game 6.
“We’re not going to change a lot. We could, and if the game dictates that we need to do that, we’re ready to do it. But we’re not going to recreate the wheel tonight. We’re going to be basically who we’ve been. Not having Perk, we may have to do it a little different, but not much.”
