Adam coached Nolan in Kelowna of the Western Hockey League this season, where despite playing through a broken wrist for much of the season, he led the team with 36 goals and was tied for second with 63 points.
Callan, who played with his brother in Kelowna for two seasons from 2016-18, had 31 points (10 goals, 21 assists) in 76 games with Syracuse of the American Hockey League this season.
Now, they will get the chance to play together again after becoming the fourth brothers to be selected in the first round of the NHL Draft by the same team, joining Dave and Mark Hunter (Montreal Canadiens, 1978, 1981), Duane and Brent Sutter (New York Islanders, 1979, 1980), and Henrik and Daniel Sedin (Vancouver Canucks, 1999).
"We've mentioned, obviously, playing junior together," Nolan said. "It's crazy to now be in the same organization in the NHL. We didn't think anything of it. We just thought it would be cool. But now I can't wait to celebrate with him."
