The No. 1 pick in the 2018 NHL Draft bonded with the Sabres' two previous first-round picks, Casey Mittelstadt (No. 7 in the 2017 NHL Draft) and Alexander Nylander (No. 8 in the 2016 NHL Draft), forming relationships with his fellow rookies that could lead to a resurgence in Buffalo.
"It's very important to be comfortable with your teammates so when the season starts, you enjoy playing together ... that's the biggest thing," Dahlin said. "On the ice, you talk a lot out there with your friends and you compete together, do something together, and that means a lot."

While Dahlin, the 18-year-old phenom from Sweden, will likely be a top-two pair defenseman out of training camp, forwards Mittelstadt and Nylander are looking to earn fulltime roles.
All three players made a strong showing at the Prospects Challenge. Dahlin had two goals and an assist in two games. Nylander had three goals and two assists, and Mittelstadt had three assists in three games.
"[Mittelstadt] was a great, funny guy," Dahlin said. "He's young and so skilled out there. Everyone knows how good he is and I enjoy hanging out with him.
"[Nylander] is Swedish so he talks a lot of Swedish with me. He's also great on the ice, can score from everywhere and he has great stick-handling and hockey sense."
Mittelstadt, 19, had five points (one goal, four assists) in six games with the Sabres at the end of last season. He signed a three-year, entry-level contract March 26, and scored his first NHL goal against the Tampa Bay Lightning on April 6.
