They said the Yankees would rebuild this season and the Jets had a great shot at the No. 1 overall pick and an 0-16 record. They said the pitching-rich Mets were headed to another World Series and the Giants to another Super Bowl.

Four New York sports examples of Kevin Garnett’s famous mantra “Anything is Possible.” Or, in the case of the cursed Mets and winless Giants, impossible.

The Knicks’ preseason is over, ending Friday in a tightly contested 110-103 loss to the John Wall-less Wizards as the club finished winless at 0-5. It ended with their two young gems, Kristaps Porzingis and Frank Ntilikina sitting it out on the sidelines with injuries.

Nothing went right during coach Jeff Hornacek’s first training camp without Phil Jackson lurking. Hornacek even got beat up by a Manhattan traffic jam Friday and arrived 45 minutes late to the Garden.

From management to the coaching staff, an emphasis on defense was promoted. Instead, the defense allowed 112 points per game this preseason, looking as bad as that of last season’s club, which finished with a 25th-worst defensive rating.

“The practices have been great,’’ Hornacek said, searching for a silver lining.

Next time the Knicks step onto the court, Carmelo Anthony will greet them Thursday in Oklahoma City. It has the makings of a prairie rout worse than Custer’s Last Stand — the potential to be Anthony’s greatest night since Syracuse won the title.

But remember, nothing has gone according to plan in New York sports this year. The trade of Anthony — even if it had been for one of Thunder general manager Sam Presti’s immaculate suits — was a no-brainer. The Knicks would have been a losing team with or without Anthony this season because of their point-guard dilemma.

At least a 25-and-under ideology is being employed — with an offense featuring pick-and-rolls and fast tempos rather than triangle sets the players treated as more intricate than trigonometry equations.

Knicks fans would feel better if Ntilikina played the five preseason games like he did the first one — smoothly running the show and more than competent on defense. Instead, he sat out the final four games with a bruised right knee, creating durability concerns. All the while, a new gigantic Nike Ntilikina billboard is now up on a high-rise, hovering above the Garden.

Porzingis, too, was hardly a force. In playing just one full game and half of another, Porzingis failed to show the low-post improvement he claimed to have made over the summer in starring for Latvia’s National Team.

There was a bright side. The two players the Knicks got for Anthony and their premier free-agent signing, Tim Hardaway Jr., were October shining lights. They combined to shoot 23 of 35 in Friday’s finale.

Enes Kanter, scoring 15 points Friday, has all but earned the starting center job over Willy Hernangomez with his energy on offense. Doug McDermott showed flashes of his offensive gifts and staged a downtown fireworks display Friday (21 points in 23 minutes). Hardaway led the team in preseason scoring on 49-percent shooting, and notched 23 in the finale. All part of the young corps.

Now the real show begins — and it may look ugly in Oklahoma City. But a lot of general managers believe Porzingis is headed for All-Star status this season. The Knicks need him to be the franchise’s superstar if they are to be a legitimate factor in years to come.

The chances of that happening for Porzingis this year? Probably better than Aaron Judge’s chances had been of becoming a strong 2017 MVP candidate. In fact, Porzingis has eight inches on the 6-foot-7 Judge and has a better 3-point shot.

As Ntilikina sat, the guards the Knicks passed on in the draft excelled: Dennis Smith Jr., Malik Monk, Donovan Mitchell. None of them quarterbacked their team to the French League finals against grown men last June. The translation for the word patience in French is … patience.

Meanwhile, The Tank Police are hoping for the Knicks to lose famously. As fans learn about forwards Michael Porter Jr., Marvin Bagley III and Luka Doncic, the Tank Police will root for the third seed in May’s lottery.

It’s a lousy way to support your team before Halloween. Let’s see how it shakes out. There are only five real teams in the Eastern Conference: the Wizards, Cavaliers, Celtics, Raptors and Bucks.

“I think every time guys step on the court, they think they’re going to win the game,’’ Hornacek said. “If you say that to those guys in the locker room, they’ll probably flip you off. They don’t expect to lose. That’s the right attitude to have.’’

In other words, don’t Judge them yet.
