Sunday’s Game 5 of the NBA Finals marks the Celtics’ last game at the Garden this season.

 

That may or may not be a bad thing.

 

Sure, the C’s had a winning record at home during the regular season, but their 24-17 mark was tied for the worst of any playoff team.

 

But then came the playoffs. Boston was 7-3 at home going into Thursday night’s Game 4 against the Lakers, including the clinching game of each of their first three series — Game 5 against Miami and Game 6 against both Chicago and Orlando.


“Our intensity level goes up a little bit higher [in the postseason],” Glen Davis said. “Our approach to the game is a little different.”


The Celtics have stepped it up at home. And the fans have, too.


“The place is rocking, you know,” Kevin Garnett said. “I can’t even hear half the calls in here because it’s so loud.”


The C’s have responded to the Garden crowd’s deafening “De-fense!” chants, allowing a playoff-low 92.0 ppg at home.


Now for the bad news: If the C’s are to win the NBA Finals, they’ll have to do it in Los Angeles.


Boston boasts a 6-4 road record this postseason, a far cry from their 3-12 road record two seasons ago when they won it all.


Of course, they know what they have to do to bring the trophy home.


“We have to be more focused,” Davis said. “We have to be more in tune, more intact, because we’re going to have to win this thing on the road.”
