Mike Woodson isn’t changing his lineup, Carmelo Anthony will keep shooting and the Knicks say they will start redeeming tonight.

The Knicks face a genuine must-win Game 2 against the Pacers, who took Game 1 of the second-round series, 102-95, Sunday at the Garden. A loss would put them down 0-2 heading to Indiana, where the Pacers beat the Knicks both times in the regular season.

“We don’t want to do that,” Anthony said after yesterday’s practice. “We want to take care of business on our floor. We felt we gave them a game, which we did. We’ll redeem ourselves [tonight].”

History is against the Knicks, who are 0-5 in playoff series in which they drop the first game at home.

“It’s very critical,’’ Woodson said. “We can’t go back to Indiana down 0-2. We got to do everything we can do to win the game.”

Anthony is shooting an awful 38.1 percent in the playoffs and has shot an even worse 35-of-110 (31.8 percent) in these last four playoff games.

“I feel the shots I’m taking I should still take,” Anthony said. “I feel those shots I can make. I’m going to keep shooting. We’ll be a much better team [tonight].”

Woodson said he will keep Anthony at power forward for now and not make a panic move to a bigger starting lineup. Kenyon Martin raised the possibility after Sunday’s loss that a foul-plagued Anthony is getting beat up on the block and the Knicks may want to match the Pacers’ size up front.

In a switch to a more traditional frontcourt, Martin would start at power forward, Anthony would slide to small forward — away from the Pacers’ burly David West — and guard Pablo Prigioni would head to the bench.
