It wasn’t so much J.R. Smith who looked sick, and it wasn’t so much Amar’e Stoudemire who looked rusty, it was the rest of them.

Neither Smith nor Stoudemire conjured up memories of Willis Reed limping through the Garden tunnel for Game 7, but don’t blame Game 3 on either of them.

Blame the rest of the New York Sicks, 82-71 losers Saturday night to the Pacers.

Smith (4-for-12, nine points) played through his virus and actually looked better than when he had been healthy lately, and Stoudemire (3-for-8, seven points) gave coach Mike Woodson more than he could have hoped for in his long-awaited 8:56 return from his latest knee surgery.

No offense, but the Sicks’ offense belongs in the infirmary.

* Carmelo Anthony (6-for-16, 21 points) scored 19 of the Knicks’ first 41 points. He didn’t score a basket in the fourth quarter.

* Raymond Felton? Nothing much.

* Jason Kidd? Not enough, except on the boards.

* Tyson Chandler? Not nearly enough — again — against Roy Hibbert.

* Pablo Prigioni? Not much.

* A shot clock violation when you are trailing 70-57? Are you kidding me?

Woodson: “Offensively we just didn’t have anything.”

Stoudemire: “We’re a much better scoring team than what we displayed out there tonight.”

Chandler: “We’re playing as individuals. We’re not making that extra pass, so you’re not seeing as many attempts because we’re playing a lot of one-on-one basketball.”

Smith: “I think we have to start the game off with moving the ball.”

Smith had the chills following his shower, but vowed to play Game 4.

“It’s playoff time,” Smith said.

Despite the Knicks’ offensive ineptitude, they hung around until early in the fourth quarter even as they were getting hammered on the offensive glass mostly because the Pacers missed 23 of their 33 3-pointers.

Smith left the bench with 5:26 remaining in the third quarter. Anthony missed a chippie follow and a short baseline jumper, and Paul George drilled a 3 and it was Pacers 56, Knicks 44. Smith clanged a 3 from the left wing off the back rim. With 3:17 left in the third quarter, Anthony took his three fouls to the bench and in came Stoudemire.
