A crowd that backs its team definitely helps...the players feed off the crowd's vocal support.
A couple of quotes from our first playoff game against Atlanta in 2008:
"You hear the crowd. You hear the building rocking. The bleachers were shaking and I was the last to run out." -KG
Every seat was more or less filled as the national anthem was sung. As the Hawks were introduced, the hometown crowd drowned it out by chanting, "Let's Go Celtics!". The crowd roared when the Celtics were introduced.
"It was phenomenal," said Celtics coach Doc Rivers of the atmosphere. "It's funny. It's rare when you can hear the fans in the locker room when the teams run out. Today you actually could."
I also remember the fans chanting "Rondo is better" whenever Bibby went to the FT line. It doesn't matter if he was at that point in his career but such crowd behaviour has the potential to effect a player's game.
And this from that excellent series against the Bulls last year:
The Celtics were pushed by a highly energized capacity crowd at the Garden during Game 7 with the noise level rising at numerous junctures.
“The crowd was phenomenal,’’ said Brian Scalabrine. “When we needed a defensive stop, they stepped up, and the good, old Boston crowd, they were probably hitting it early today.
“They got us going and geared us up. You can tell the buzz in the air. When they do the ‘Celtics’ chant’ in the warmup line, you know it’s going to be a great night.’’
This is what Shelden had to say on the opening night against Bobcats:
"I had heard a lot about the crowd in Boston and I want to see how loud it can get on a nightly basis. I know from playing as a road player here that there is great fan support, and sometimes you really need that."
Whether we want to believe it or not...an energized home crowd surely helps.
