PHILADELPHIA For most of Ray Allen's career, judging his impact on games was pretty easy.
Allen's value was often measured in how many points scored, or how many dagger 3-pointers he made to help his team win.
But these days, Allen's statistical impact isn't quite as great. Allen is averaging a playoff career-low 11.3 points and in the three games against Philadelphia, he's averaging just 10.7 points per game.
However, his ultimate contribution to the Celtics in terms of winning, could not be any greater.
When you look at all the factors that have played a role in Boston's 2-1 series lead over the Philadelphia 76ers, Allen's mere presence ranks high.
The Celtics are plus-22 when Allen is on the floor, the highest plus-minus ratio of any one in this series with the exception of Kevin Garnett (plus-47) and Avery Bradley (plus-23).
"That tells you his effectiveness," said Sixers coach Doug Collins, who like most coaches who face the Celtics, has paid a great deal of attention to Allen when he enters the game.
"Ray Allen, he's a threat to throw up 20 points any time," Collins said. "When he's on the floor, you have to space him differently. He takes away some of your help because you have to shade him a little bit more than you do somebody else."
While it might be tempting to try and force Allen's involvement more in Game 4, don't think for a minute that the NBA's all-time 3-point shooting king will do any lobbying for more shot attempts.
"I don't have to change anything (in Game 4) that happened from last game," Allen said. "The way they guarded me, the way they guarded us as a team, the final score was the result we were all hoping for. The object is to win."
