INDIANAPOLIS – As the clock pushed into early Saturday morning, J.R. Smith awoke freezing, chills running through his body, and sickened with a virus. Treatments had started ferociously then, and the New York Knicks’ doctors began giving Smith fluid, trying anything to get him in playing capacity.

Smith had been consistent offense in the regular season, a Sixth Man of the Year, revitalizing himself as a force the Knicks can’t win without. They need his shooting and the way he creates plays, but he’s settled for jumpers and played unsteady too often in these playoffs. Smith never felt like himself Saturday night, and his voice was groggy and he lacked energy in his shooting.

For Smith, the walk out of the Fieldhouse couldn’t come sooner after the Knicks had lost to the Pacers, 81-72, in Game 3 of this conference semifinals. Smith rose for eight jumpers on Saturday, coming up short on several, and appeared out of place on some offensive possessions. With his head down heading toward the team bus late Saturday, Smith perked up to greet a Knicks official and let out a truth that has haunted him throughout the playoffs: “Just missed shots, man.”

In all, Smith missed eight of 12 from the field, slipping to just 11 makes in 42 attempts for the series. Just minutes into entering the game, Smith already had his hands on his knees and was admittedly winded. Nevertheless, the Knicks badly needed Smith on a night Carmelo Anthony took a beating, took the least amount of shots he has all postseason, and no one else scored more than nine. The Knicks know this is what the Pacers do: Slow the pace, muck up the game and close off the three-point line.

Amar’e Stoudemire did play for the first time since March, logging just eight minutes and wearing bulky casts of ice around both knees on the bench. He’s discussed with Mike Woodson that his limit is 15 minutes, and clearly Stoudemire won’t be the savior of these Knicks and their offense that revolves around how Anthony and Smith attack.

All the time sidelined has given Stoudemire heightened prospective about the Knicks, and he understands the offense’s limitations when Smith doesn’t assert himself, doesn’t weave through defenses for drive and kicks. Never mind in a Game 3 when two rotation players (Pablo Prigioni, Jason Kidd) went scoreless and Tyson Chandler dealt with foul trouble because of Roy Hibbert’s immense paint control.

“It was difficult for [Smith] out there,” Stoudemire said. “He’s still under the weather, not feeling great. Hopefully he feels better by Game 4.”

Smith, for his part, believes he has either a stomach or nasal virus and he was adamant he’ll play on Tuesday night – whatever treatments await him. “I don’t know, but I’m still playing. Being sick doesn’t really matter,” he said.

From one end to another within the Knicks’ locker room, players believed the Pacers aren’t using any different schemes, but rather they’re simply missing shots. Truth is, Indiana has the bodies, the defensive structure and the manpower in Hibbert, Paul George, David West and George Hill to destruct New York’s gameplan in a way that the depleted Boston Celtics couldn’t in the first round.

“It was a bad offensive game and we couldn’t put the ball in the basket,” Ray Felton sighed.

The Knicks have come to rely upon the brilliant scoring and one-on-one abilities of Anthony and Smith, but Anthony kept getting crowded, kept getting hit, and Smith never shook off the chills. Anthony’s talent has widened the Knicks’ margin for error in stretches of these playoffs, and yet the Pacers are determined to show he won’t have those scoring binges on them. This is where Smith has been so valuable, so consistent in proving opponents’ efforts futile.

Smith had gotten a virus and sat for dinner here Friday night, wondering how worse it would get, wondering if he’d play. Sure enough, there was no flu game out of J.R. Smith on Saturday – just shots going awry, shots falling short, and a teetering, welcomed walk out of the Fieldhouse and into recovery time to find any resemblance of the Sixth Man.
