Brock Motum says being invited to a NBA training camp with the Utah Jazz is a great opportunity, but that won’t mean anything until he makes the team.

Australian big man Brock Motum knows he’ll have to be ruthless if he’s any chance of breaking into the NBA.

The 208cm forward this week accepted an invitation to a training camp with the Utah Jazz after impressing in the Las Vegas Summer League.

Motum starred alongside countryman Dante Exum in the tournament, with some pundits claiming he outshone the Jazz’s No.5 draft pick.

The Brisbane-born 23-year-old is no stranger to US basketball, having spent three seasons at Washington State university.

After graduating last year, he completed nearly a dozen pre-draft workouts and spent a week at a mini-camp with the Philadelphia 76ers, although none led to a spot in a Summer League squad.

But since being picked up by Italian top-league side Bologna, to whom he’s contracted, Motum has flourished – ultimately earning a call-up from the Jazz.

“It was a great opportunity, but it doesn’t mean a lot,” he told AAP from Canberra, where he’s training with the Australian Boomers for next month’s World Cup in Spain.

“I still have to prove myself. I still need to keep improving and playing well.

“It was a great thing at the end of Summer League to find out (I got an invite to the Jazz training camp in September), but it doesn’t mean anything until I make the team.”

Getting court time with Exum – who he reckons will be a superstar – and a host of other NBA players and prospects reinforced to Motum just how hard it is to make it in the big time, but he’s determined to push on.

“They’re the top of the top,” he said.

“It’s a really competitive environment and you’ve got to bring your A-game.

“There’s always guys out there that are trying to get a spot that you don’t have … so you can never be content. That was the main thing I learnt.

“More than anything, it just refreshed in my mind that you always have to keep working.”

Motum said the likes of Patty Mills, Aron Baynes and Andrew Bogut had helped pave the way for up-and-comers in the NBA by sticking to the “Australian way” of playing.

“I think the Australian stereotype is that we’re hard-nosed, we play hard, we do the little things – the blue-collar players, kind of,” he added.

“They’ve left a good mark for us … and I think that helps the next generation come through.

“As long as we stay true to the Australian way, I think it’ll continue to be like that and, hopefully, we can keep bringing more guys into the NBA.”
