The calendar says November.

But it certainly looks like last May for the Knicks J.R. Smith.

Smith, in his fourth game back from an NBA-imposed five game suspension after a rehab for offseason knee surgery, shot Saturday as if the Hawks were the smothering Pacers of last season’s playoffs.

When Smith finally exited with 3:41 left in the Hawks 110-90 wipeout victory, he wore a look of total disgust on his face.

“Excuse my language, but I was playing like [garbage],” Smith said after his latest nightmare, a 3-of-18 horror that left his season shooting percentage at 22.6 percent. “I played terrible. I’ve been playing terrible since I got back and I wasn’t happy about it.”

In fact, Smith, who shot a dreary 28.9 percent against the mighty Pacers in May, has been so terrible, coach Mike Woodson admitted he will “re-evaluate” his starting alignment, among other worrisome tidbits. Smith has started after his Sixth Man of the Year Award-winning season.

“I’ve got to go back and re-evaluate some things,” Woodson said after he was clearly disturbed by the Knicks’ lack of effort. “I’m not just blaming it on J.R. Offensively, you’re going to miss shots. There are nights you just can’t throw it in the ocean, but there’s no excuse why you don’t give effort defensively.

“I’ll have to go back and look at some tape and do some thinking about our lineup. I’m going to continue to shuffle and do things I think are right by our team to try to find the right combination.”

The way matters unfolded Saturday, Woodson could have shuffled until Doomsday and not come up with a proper combo. Smith probably could have continued shooting until then, too, and found similar results.
