TORONTO — The Nets have shown even shorthanded they can beat good teams at home. Beating contenders on the road is another matter, and the Raptors are a constant reminder of just how far away they are.

The Nets came north and got smothered defensively yet again by the defending champions and emerging star Pascal Siakam, losing 110-102 before a sellout crowd of 19,800 at Scotiabank Arena.

Siakam had a game-high 30 points, 11 rebounds and five assists, all while leading a Raptors defense that harassed the Nets all night. In a game delayed to re-level the rims, the Nets (13-12) shot like the rims were shot glasses.

Brooklyn shot 12-of-46 from 3-point range, while watching the Raptors (17-8) hit their first seven, digging a hole they never got out of.

“The first quarter, they got hot and got going. I didn’t love the way we contested shots. After that, we settled down,” coach Kenny Atkinson said. “We knew we were going to get 3s, we just had to knock them down.”

The Nets got blocked 10 times, and committed 20 turnovers to hand the Raptors 29 points. They mustered just 10 themselves off Toronto miscues.

And though Spencer Dinwiddie’s 24 points led five Nets in double figures, they just couldn’t knock down open shots, much less contested ones. Garrett Temple was 2-of-14 from deep, and last season’s 3-point champion, Joe Harris, was just 1-for-6. It was that kind of night.

“They went 9-of-10 in the first quarter. It’s going to be pretty tough to win when I go 2-for-14 from 3,” Temple said. “We got the shots that we expected to get and are comfortable with. We’ll take those 100 times out of 100, just got to knock them down at the end of the day.”

The Nets have dropped 16 of 17 to the Raptors, including nine straight in Toronto.

The Raptors don’t look any less potent led by Siakam than they did winning the title with Kawhi Leonard last season. The Nets tried Taurean Prince, Dinwiddie and even reserve David Nwaba on him, all to no avail.

Then there was Siakam’s defense, like chasing down Rodions Kurucs in transition for one of his three blocks on what seemed like a sure fast-break dunk late in the third. It typified the evening.

“We could’ve played better in terms of energy,” said Jarrett Allen, who grabbed 10 rebounds but was largely outplayed by Raptors veteran Marc Gasol (17 points, 15 boards).

The Nets had some fool’s gold early, after Dinwiddie’s rare four-point play gave them a 12-2 lead. But they never came close to slowing Siakam and Norman Powell (25 points) on the other end.

Toronto couldn’t miss, making their first seven 3s. Kyle Lowry hit from behind the arc to put the Nets in a 26-21 hole. It just got worse from there, the Nets falling behind 47-31.

Brooklyn did reel off 11 unanswered points, a DeAndre Jordan basket getting them within five. That was the margin at the break, with the Nets going into the locker room down 65-60 after a Prince 3-pointer capped an 11-3 run.

Prince hit another to pull them within 67-65 right after the half. But they coughed up an 8-0 run on their way to losing the front end of a tough back-to-back, hosting the Sixers on Sunday.

“We missed shots we usually make,” said Prince, who had 14 points and 10 boards. “That’s their job to contest everything: Our job is to continue to move the ball. This is the NBA, so you have to hit shots when people are right in your face.

“We lacked intensity on the transition defense. For the most part we were stopping them in the half-court, but we could’ve done a better job in transition. That’s on us.”
