Well, then. That was certainly a sobering couple of hours at the world’s most famous arena.

Every time the Knicks have slipped on a banana peel this season, there was always an explanation: This player was out. That player was out. The other team was better, more rested, not playing a back-to-back. There hadn’t been that many slips, truth be told, which is how they were still 15 games over .500 stepping onto the Garden floor last night through 49 games.

They walked off 14-over after 50.

And suddenly it isn’t a reach to wonder if we haven’t already seen the best of the Knicks this year. This 92-88 loss is that concerning, that upsetting if you still harbor the belief that the Knicks remain the equivalent of the East No. 2 seed they still carry into the All-Star break with them.

Even if it’s never seemed more tenuous.

“I’ve got to sit the next three or four days and think about these last two losses,” Knicks coach Mike Woodson said, maybe half an hour after the final boos had dissolved and the last disgruntled customer had vanished behind the Garden walls. “We’ve got to get back and try to figure out how to get back to where we were early in the season.”

Suddenly you have to wonder what the Knicks have in them across the season’s final 32 games, starting next Wednesday night in Indianapolis against a Pacers team that clearly believes it’s every bit worthy of that 2 seed as the Knicks are. And it will continue forward, all the way through a March that promises to be a hellacious gauntlet for the Knicks with 18 games in 31 days, 10 of them on the road, five of them on the West Coast.
