DURHAM — With all the new faces that have donned a Duke basketball uniform over the last several years, few remain constants.

An influx of 5-star caliber players each season means one-and-done players come and go, and in that short time many leave a lasting impact.

Then there’s Justin Robinson, the fifth-year senior, who more often than not is on the bench.

In rare extended playing time Monday night, Robinson showed Cameron Indoor Stadium spectators his impact — one his teammates see regularly in practice — providing the on-court spark that lit the fuse of an 88-69 blowout victory against North Carolina State.

“Any time I get a chance to play, I want to bring energy. I want to bring leadership and talk. Luckily, I got a couple of shots to fall early, so that helped a lot,” Robinson said. “We needed a little more energy, especially on defense. And then once our defense picked up, our offense always follows, we get the transition buckets you see, like Cassius (Stanley) throwing down lobs. That always brings our energy up, too.”

More energy should be required in the latest installment of the Atlantic Coast Conference rivalry when the No. 7 Blue Devils play host to North Carolina Saturday evening. Duke won 98-96 in overtime when the teams met last month in Chapel Hill.

Robinson’s vigor resulted in a season-high 10 points and a career-high six rebounds in almost 15 minutes of productive playing time against the Wolfpack. He averages fewer than five minutes a game in 54 career appearances.

“(Duke coach Mike Krzyzewski) said, ‘Good work, way to bring a lift, and on to the next one.’ He’s always been very positive with me throughout the years while I’ve been growing,” Robinson said. “So even though I haven’t gotten the minutes, I feel like my teammates have had a lot of confidence in me, so when they called my number, I was ready.”

The forward played a combined 63 minutes in the 13 games he previously saw action in this season. Fifteen of those minutes came two games prior when he finished with six points and three blocked shots in the Blue Devils’ 113-101 double-overtime loss at Wake Forest.

The son of Naismith Memorial Basketball Hall of Famer David “The Admiral” Robinson, the younger Robinson said he stays prepared for opportunities like those.

“Just practice every day. Going up against people like Vernon (Carey Jr.), Matt (Hurt), Javin (DeLaurier), it’s not easy,” he said. “So you have to be ready just for practice, and when you come into a game, it’s the same stuff you do every day, all the drills you do. You just have to know that you can do it.”

Robinson came to Duke as a preferred walk-on, redshirted the 2015-16 season and later earned a scholarship. Regardless of the level of his prep accolades, his teammates weren’t surprised by his performance.

“Every time he steps on the floor, something good happens. Not only in the games — in practice, he brings it every day. He’s one of our best players,” said one of Duke’s former touted prospects and now a freshman forward, Wendell Moore Jr. “He talks a lot, and he knows what he’s doing because he’s been here. He’s been in these situations and he helps all of us young guys out a lot.”

The Blue Devils missed 12 of their first 15 shot attempts Monday night and trailed N.C. State 20-12 when “J-Rob,” as those in the Duke program call him, stepped up and made two 3-pointers in a little over a minute span.

“Sometimes you just can’t hit. Sometimes the putt won’t go in. They weren’t doing it. We made some changes. That’s where J-Rob and Jordan Goldwire, really — I know J-Rob played well, but Goldwire was sensational,” Krzyzewski said. “For these kids, it means so much and they take too much responsibility and then it affects them in the next play.”

In the graduate senior, the Blue Devils have a player who has the experience, maybe not a plethora of it on the court come gametime, but more than enough when it comes to the work behind the scenes.

“In the last month, he’s just played really well in practice. J-Rob, even for (the N.C. State) game, is on the scout team because he knows everything. (Assistant coaches) Jon (Scheyer), Chris (Carrawell), Nate (James) … whoever has the scout, when they get them all together, J-Rob is telling them all what to do,” Krzyzewski said. “He has a voice that everyone listens to. Chris Carrawell had the (N.C. State) game. Chris put words on the board, not a game plan, and then he had J-Rob speak. To try to get everyone to have ownership — he’s owned it the longest. What a good story he is of persistence.”
