If you were late tuning into Game 2 of the Nets’ dismantling the Celtics, you might have missed a fairly breathtaking stretch about midway through the first quarter when Brooklyn ripped off 15 straight points and firmly declared this was going to be a different game from Game 1.

The stretch was not achieved by James Harden, Kyrie Irving or Kevin Durant, though they produced ooh and ahs at various points of the dominating 130-108 rout. Instead, it was done by Joe Harris, who hit three of his seven 3-pointers in a captivating 59-second span that made the outcome a forgone conclusion.

“That’s a shooter’s dream right there, especially with this group,” Harris said. “Obviously, you’re trying to make it as good of an offensive possession as you can, but those guys were looking for me early on after I got the first couple to go.”

It is a dream or luxury to possess the NBA’s leading 3-point shooter surrounding any star trio. It also is a dream for someone like Harris to get the kind of looks he got with how well the Nets darted the ball through the lane and back out to the perimeter for most of the night, doing pretty much what they focused on in practice after getting it done with an uneven showing in the series opener.

“Tonight, it was a lot of stuff that we worked on in practice in terms of spacing, getting to our spots and trying to make the extra pass, too. We saw in Game 1 how much they collapsed when guys get into the paint or even how keyed in they were with Kyrie, James in a lot of situations.”

The first three came from the right corner off an Irving pass, the next one came in the left corner off a Durant pass. The third three came from the left corner off a bullet pass from Irving that soared over the lane and Harris released the shot as Evan Fournier made a futile attempt to defend it.

Harris then hit his fourth after Tristan Thompson fumbled the rebound to Harris, who then passed to Blake Griffin and quickly got the return feed from the right side.

His fifth 3-pointer came off a quick pass from Harden, the sixth after Irving screened Marcus Smart and Griffin did the same to Kemba Walker, who regrouped only to get to Harris by seconds after the shot was released from the left side.

And to cap off the barrage, the final three developed in a terrific three-way passing sequence. Harden whipped a bounce pass in the lane to Griffin who was deep in the low post. Griffin quickly dispensed the ball to Durant who whipped it over to Harris for an uncontested corner 3-pointer in front of his rejoicing teammates on the bench.

Harris was so effective that if the Celtics were more competitive, it is likely he would have set the franchise record for 3-pointers in a playoff game. Instead, he settled for tying the mark set by Deron Williams on April 27, 2015 in Game 4 of the first-round against the Atlanta Hawks in the last gasps of Brooklyn’s original attempts at attracting stars.

About 15 months after Williams set the franchise postseason record for 3s, the Nets signed Harris as they embarked on a rebuild. At that point Harris only had 56 games under his belt and had made only 32 of his first 88 3-point attempts after he was a 40.7 shooter in four seasons at Virginia.

In the first season with the Nets, he improved to 38.5 percent. By the second season Harris was up to 41.9 percent and in year three as the Nets won 42 games, reached the playoffs and caught the attention of Durant and Irving, he led the league at 47.4 percent while also shooting 50 percent. Last year Harris was down to 42.4 percent but this year while missing only three games, he led the league at 47.5 percent and hit at least five 3-pointers 13 times.

“It makes it tough on the opposing team just to stay disciplined in defensive sets when you’ve got Joe Harris making shots like that,” Irving said. “It creates open opportunities for us to drive. When we’re playing like that, it definitely makes the game a lot easier.”

With how the Nets moved the ball to get Harris those looks it never looked easier than how it did in Game 2, putting Brooklyn halfway to a sweep.
