At least one kid was moved to tears and a whole bunch of adults weren’t very happy when NBA commissioner Adam Silver announced the Knicks had selected Kristaps Porzingis of Latvia with the fourth selection of the NBA draft.

From all the booing that echoed around Barclays Center on Thursday night, you would have thought beer sales ended early. Instead the reaction was in response to the Knicks’ decision to draft Porzingis, who is generally regarded as a 7-foot-3 jump shooter who won’t make much of an impact for two or three years.

“I have no idea what Phil Jackson is thinking,” said Mark Dantuono, 17, of Staten Island. “Maybe he thinks he’s going to be the next Pau Gasol, but I don’t think so. This is the worst thing I’ve ever lived through as a Knicks fan. He didn’t score that many points in Europe. What’s he going to do in the NBA?”

Joseph Mangiero, 18, of Staten Island, was also unhappy with the choice.

“I have no words. It’s that bad,” he said. “It will actually bother me if he does something in the league because I’m talking like this. But from what I’ve seen on TV and from what I’ve heard, this is not good.”

It’s a tough ask for Knicks fans who went through a year of unprecedented losing to rally around a player who is projected to need two or three years before he begins to reach his potential. At 233 pounds, Porzingis is as thin as a lamppost and may struggle early with the physical play in the NBA. He’s not a big rebounder or a shot blocker, but more of a tall perimeter shooter in the mold of Dirk Nowitzki, someone who could open up the floor for Carmelo Anthony.

Sounds good in theory, but the reality is since Yao Ming was drafted in 2002, 19 international players have been selected in the NBA lottery and none has been named an All-Star.

“We don’t have two or three years to wait for a player to develop, especially somebody who is the No. 4 pick,” Dantuono said. “We have Carmelo Anthony, who’s getting old. We don’t have time to wait for anything.”

The negative reaction from Knicks fans at Barclays Center had to do in part with their lack of familiarity with Porzingis, who played in Spain. After the Timberwolves did as expected and selected Kentucky big man Karl-Anthony Towns with the first overall pick, the Lakers took Ohio State guard D’Angelo Russell before the Sixers snagged Duke forward Jahlil Okafor.

Watching Okafor taken with the third choice irritated Knicks fans. The selection of Porzingis felt like pouring salt in the wounds, especially with Duke forward Justise Winslow and guard Emmanuel Mudiay, who played in China last season, still available.

“I just don’t like the Porzingis pick,” said James McCauley, 21, of Brooklyn. “I’m not a fan. Every tall Euro guy they compare to Nowitzki. But I don’t think there’s ever going to be another Nowitzki. Porzingis might have good fundamentals, but he’s got a serious problem in the weight department and the Knicks need a big banger down low.”

Porzingis heard the boos and hopes to turn them into cheers.

“I know the fans are a little harsh sometimes,” he said. “But that’s how it is here in New York and I’m ready for it.”

Not everyone was booing. Antonio Manno, 21, of Brooklyn said he likes the choice and can be patient for Porzingis to develop.

“He’s 19 years old and he’s going to work hard,” Manno said. “He can shoot and he can run the floor and he’ll open things up for Carmelo. He said it’s his dream to play for the Knicks. He’s going to play hard for the city.”

Porzingis will get his chance to prove Manno right and those who doubted him wrong. Maybe years from now, he will look back and smile about the night the mention of his name made kids cry and adults angry.
