Goran Stubb, the NHL Director of European Scouting, is as curious as anyone to see how Dahlin responds during his first season.
"The expectations from the fans is enormous, and it's not an easy situation for a teenager," Stubb said. "But if anyone can handle it, it's Rasmus Dahlin. I don't know him personally but from what I have seen on the ice and in the stands at the draft, I'm sure he can handle all surprises coming up during the season. He's always been a calm, mature young man.
"And I am sure he'll get the Sabres at least close to the Stanley Cup Playoffs already during his first season."
Sabres coach Phil Housley gave Dahlin high marks during training camp but said expectations should be tempered while Dahlin familiarizes himself with the NHL.
"He's a young man and going to make mistakes," Housley said. "One of hardest things for him is just knowing who he's playing against and the personnel and characteristics on everyone's team. It's going to take some time getting to know the players but he's pretty cool and calm. We're going to have some growing pains but I like that he still makes the plays. He'll make a mistake, but he's not afraid and very confident in his abilities, and we are too. As he moves forward I think he'll learn from these things because he's a smart hockey player."
Housley, himself a Hall of Fame defenseman, has been impressed by how far Dahlin has come already.
"His timing is really impeccable," Housley said. "He jumps into the play at the right time, and when he beats a guy he moves the puck right away and gets it up ice. The one thing I really like, every shot he takes it seems to hit the net. His development's where it needs to be right now."
Pettersson, 19, led the Swedish Hockey League with 56 points (24 goals, 32 assists) in 44 games last season, passing Kent Nilsson (53 points, 1975-76) for the most by a junior-age player. He also was named most valuable player in the regular season and playoffs after helping Vaxjo win the SHL championship with 19 points (10 goals, nine assists) in 13 playoff games.
