To a man, the Suns bristled at the suggestions that the tank was on for this season.

They might be young and inexperienced but they are also proud and hungry men with a competitive streak that got them to the NBA.

The only resemblance to a tank in the Suns play during Wednesday night’s season-opening win was how explosive and unrelenting they were in running over Portland 104-91 at US Airways Center.

The Trail Blazers now have a franchise-record 14-game losing streak, but the Suns were widely considered the worst team in the Western Conference. One night will not shift perception. But it did give credence to the rising belief in how the Suns have rebuilt their franchise.

Jeff Hornacek won his Suns head-coaching debut with a lineup that had one returning starter, Goran Dragic, from last season and navigated the nine-man rotation with two rookies, a player who sat out a season and three summer acquisitions. After about eight minutes, the Suns led 25-12 and never trailed thereafter.

“They kind of shocked us,” Portland guard Damian Lillard said.

Said Dragic: “I was a little bit surprised how we clicked.”

The Suns used their fastbreak for 31 points and got the Blazers defense out of position with a double-dose of penetrating point guards who combined for 48 points, 15 assists and 13 rebounds.

Portland was led by Lillard (32 points) and LaMarcus Aldridge (28 points), but the rest of the Blazers shot 28 percent while four Suns starters scored at least 18 points.

The revamped Suns showed promise, especially when new starting center Miles Plumlee outscored his rookie Indiana season in his first 13 minutes. Plumlee scored 13 points in 55 minutes as a rookie but posted a tail-busting double-double in the first half Wednesday night, going for 16 points and 10 rebounds while ex-Suns center Robin Lopez struggled for two points and two rebounds.

“It’s extremely gratifying,” Plumlee said. “I’ve been waiting for this opportunity. It doesn’t always come this quickly for everyone so I knew, off the bat, I wanted to take advantage of it.”

Plumlee showed how he refined his offense with two hooks and a driving score. His 18-point, 15-rebound game was the first double-double starting debut by a Suns player since Shawn Marion in 1999.

“When we first came here, we saw him in the gym (in August) and went, ‘Oh my goodness, we know we’re going to get some rebounds but that’s going to be about it,’” Hornacek said. “Our assistant coaches, Mark West and Kenny Gattison, really worked with him on footwork and we’ve seen it all preseason and in practices.”
