The Knicks know all about playing for a hurting city. They opened their season days after SuperStorm Sandy devastated the New York area, and their emotionally charged 104-84 rout of Miami at Madison Square Garden jump-started them on the way to their first Atlantic Division title since 1993-94.
"I don't even know how to put it into words, but you just wish those families nothing but the best," Knicks coach Mike Woodson said. "But you know Boston has always been a sports town, so they'll rally around it and try to figure it out as they move up the road."
The Celtics swept the Knicks in a first-round series two years ago. This time, New York is the No. 2 seed after ending Boston's five-year reign as division champion and won three of the four meetings in the regular season.
Rivers downplayed the regular-season results, noting the Celtics dominated Atlanta during the 2007-08 season, only to be forced to seven games in the first round. But the Knicks clearly have gained confidence as they try to win a postseason series for the first time since 2000.
"It's not going to be an easy series, we know that, but at the same time it's a series that we're going to win," point guard Raymond Felton said. "We've got home-court advantage, so we've got to take advantage of it."
With NBA scoring champion Carmelo Anthony and top sixth-man candidate J.R. Smith, the Knicks have been able to crack Boston's once-stout defense. But a couple of those Knicks victories came when Kevin Garnett rested, so they expect to see a better Boston team.
But even if forced to play without starting guard Pablo Prigioni, who sprained his ankle in the regular-season finale, the Knicks believe they're stronger than their teams Boston had been beating up on for years, especially knowing they get to start at Madison Square Garden.
"That was our goal to lock down home court and we did that, and now we have the opportunity to do something special, protect our home court," Anthony said. "It won't be easy, but we're up for that challenge. We're willing to take that challenge and it starts Saturday."
The Boston-New York rivalry is one of the fiercest in sports, and the teams had their heated moment in the first meeting this season, when Anthony was suspended a game by the NBA for following Garnett to the Celtics' team bus to confront him after they exchanged words during the game.
Pierce loves to hit big shots in New York and taunt the crowd after. The Celtics don't expect anything to change Saturday, no matter how much support their city is getting.
"You know, I played here. I know how crazy, the mindset of a New Yorker," said Rivers, a former Knicks player who heard 'Hey Doc, we love Boston' at the team hotel.
"But I know what they mean," he said. "They mean the city. They ain't meaning the Celtics."
Garnett expects only one type of reception at Madison Square Garden, no matter what's happening back home.
"Terrible," he said. "We're on the road, period. Playoff time, on the road, Boston-New York."
The Knicks will also host Game 2 on Tuesday night before the Celtics get to play in front of the home fans next Friday night.
