Hughes, a center who is No. 1 in NHL Central Scouting's final ranking of North American skaters, has two connections to the League. Older brother Quinn Hughes, a defenseman, was taken by the Vancouver Canucks with the No. 7 pick in the 2018 NHL Draft. Their father, Jim Hughes, has been an assistant with the Boston Bruins and director of player development for the Toronto Maple Leafs.
"He's very skilled, with his skating, hands and hockey sense, but it's how competitive he is," Quinn Hughes said of Jack. "I always felt that was the big difference in him. He doesn't care who he's playing, who's going to go at you. He's super competitive and loves the game and is so dialed in. I don't know what normal teenagers do, but he's dialed in, working out in the morning, getting the right sleep and food and everything like that. ... It's easy to respect him just because of everything he does and how he carries himself."
Quinn and Jack were at the prospects' clinic at Hillcrest Centre in Vancouver on Thursday.
"It's cool. Anytime you get to do something with your brother, it's fun, especially because next year when we're going to be pretty far away from each other, and even this year you don't get to see him too much," Quinn said. "Whenever you get these times and experiences it's very cool."
