Joshua Jefferson shows ‘some glimpses’ in delayed Nets summer league debut

LAS VEGAS — Mikel Brown Jr. isn’t the Nets’ only first-round rookie, or even the only one, with a delayed debut.

After having to wait for the trade that brought him to the Nets to finally become official — a holdup that cost Joshua Jefferson the first four games of summer league — he finally saw his first action in Saturday’s 83-76 loss to Atlanta.

For a player who hadn’t seen live action since his college career was cut short by injury, Jefferson showed predictable rust. The 22-year-old will spend the rest of the Nets’ stay in Las Vegas knocking that off.

“Definitely. [Saturday] was just the first game in four months, since March when I got hurt. So it’s really been a long time since I’ve been in a playing setting because I wasn’t able to get any practice reps either,” Jefferson said. “So, I definitely think I’m going to be fine. I showed some glimpses [of] what I can do with the ball in my hand, so just got to keep playing.

“[The] first half was good. Had some really good showings. Just getting comfortable with the guys. I never played with them before, so it’s going to be pretty foreign for me for this first time. But just good to get good reps right now. So, just continue to play hard.”

Jefferson certainly played hard, if not particularly crisply. The 6-foot-9, 240-pound forward struggled from the floor. Jefferson finished with nine points in 26 minutes, shooting just 1-for-8 and 0-for-4 from deep. His only make came on a driving layup.

“We’d both say he wanted to make more shots. He’d say the same thing,” Nets summer league coach Dutch Gailey said. “It’s the little things that he’s doing well, and it’s the first game to get him a feel. We’ll watch the film with him, come back, get practice and then we’re back at the game [against] Sacramento.

“He’ll have a better understanding of the pace of the game. … The change is a big change, especially when you haven’t played. He’s coming off an injury; he hasn’t played in a while. So, there’s a lot of stuff he did well, and there’s stuff we can help him with. That’s going to be our goal over these next two days.”

The aforementioned injury and trade delay made Jefferson’s wait longer than expected and the rust more glaring than usual.

Jefferson averaged 16.4 points, 7.4 rebounds, 4.8 assists and 1.6 steals for Iowa State, but a left ankle sprain in its NCAA Tournament opener ended his college career.

The Nets drafted Jefferson with the No. 28 pick they got in the Julius Randle trade. But with the deal not official until Friday, he missed the California Classic and opening win over the Knicks in Las Vegas.

Unable to even practice with the Nets, both the rust and unfamiliarity were obvious in Saturday’s debut.

“I’ve been training on my own, just trying to push my wind as much as I can. My body felt good; just gotta keep playing,” Jefferson said. “I’d be pleased with my activity level and how hard I’m playing. You’re going to miss shots; you’re going to make shots. So I can’t dictate how I play off of that, just your energy and your effort level.”

Still, Jefferson showed a couple of the traits that convinced the Nets to add him to a crowded power forward room behind Randle and alongside Noah Clowney and Danny Wolf.

Jefferson ripped down a rebound and went coast-to-coast for his only bucket, went 5-for-6 from the line and added a nice bounce pass for an assist.

Granted, down 75-72, he drove and kicked out to the corner, but the spacing was off to result in a turnover with three minutes left. With improved familiarity, though, his playmaking fits with the passing the Nets have been indexing.

“Just the way my passing can affect the game, making everybody feel involved, get the ball flying around. It’s easy to guard people when the ball’s sticking in one person’s hands,” Jefferson said. “So as long as I can continue to show that with the team, we’ll be fine.”
