Two areas Hughes identified as focal points for the offseason are his strength and his willingness to shoot the puck more.
For Hughes (5-foot-10, 170 pounds), getting stronger is a must to handle an 82-game NHL season. To help with that, Hughes spent time working with Andy O'Brien, director of sports science for the Pittsburgh Penguins, who counts Penguins center Sidney Crosby and Colorado Avalanche forward Nathan MacKinnon among his clients.
"I think I've had a really good summer, personally," Hughes said. "And I feel really confident and really good in my body and my abilities right now going into (training) camp."
He also understands that being known only as a passer will make him easier to defend. Last season, he had 260 shots on goal in 50 games, second on the USA Hockey National Team Development Program Under-18 team. He also had 78 assists, an NTDP record, and holds the program record for career assists (154).
"I think in the NHL I have to shoot more," Hughes said. "Defenders are so good, long sticks, they can skate. So I have to get the puck off quick. I want to be a dual threat, a guy that can score from 40 feet away but also find the backdoor guy. I've got to find the fine line between the two. Over time I will."
One player confident Hughes will make a smooth NHL adjustment is his older brother, Vancouver Canucks defenseman Quinn Hughes.
When asked if his brother was NHL ready, Quinn simply said, "Yes."
As a result, Quinn said he hasn't felt the need to give Jack much advice.
"He's a pretty smart kid and he'll figure it out on his own," Quinn said. "Just work hard, be smart, stuff like that. Simple stuff."
Jack said he has goals for the season in mind but wasn't willing to divulge them.
"I have personal thoughts in my head, personal goals," he said. "I won't be throwing any numbers around, crazy stuff. This is the NHL. I've never done it before. I want to come in and be an impact player right off the bat, no doubt. I think New Jersey is hoping for the same thing from me."
