The Boston Celtics have the luxury of two days of rest entering Saturday's Game 7 showdown against the Philadelphia 76ers. But how much will it help their veteran legs?

The Celtics were 4-5 during the regular season with at least two days of rest before games (including the season-opener on Christmas Day in New York). During the postseason, they are 2-1 with at least two days rest, including a 16-point Game 5 win over the 76ers. Even still, their numbers overall are not as good with extra rest.

With 0 or 1 days of rest, Boston is 40-26 (.606) this season while averaging 91.8 points per game and shooting 45.7 percent from the floor. With 2+ days of rest, Boston is 6-6 (.500) while averaging 88.7 points per game and shooting 45.4 percent from the floor.

Celtics coach Doc Rivers still believes the rest can help.

"I think we do [have enough in the tank]," said Rivers. "The couple days have helped, there's no doubt about that. Listen, you don't know, You never know what you have in the tank until you start the engines and you find out. It didn't look like we had a lot the other night, I can tell you that. I made a comment to our coaches in the first quarter when I saw about six jump shots hit the front rim early, and I was like, 'This is not a good sign.' But I was hoping it was just missed shots. Unfortunately it continued."

Keep an eye on Boston's jump shot accuracy early for an idea of whether the extra time off benefitted them.
