“He’s a great shooter,” said Brad Marchand, who spoke with Wahlstrom before Saturday’s 5-1 win over the Vancouver Canucks. “He has a very, very dangerous shot. He’s almost like a big Pasta the way he can shoot the puck. He’ll be a weapon in that aspect.”

Pavel Zacha had a goal and two assists and Jeremy Swayman made 19 saves for the Bruins (16-13-3), who had lost their first two games of this five-game road trip by a combined score of 13-2. Boston improved to 8-4-0 since interim coach Joe Sacco replaced Jim Montgomery on Nov. 19.

Long before the Bruins claimed him off of waivers on Saturday, well before he was drafted in the first round of the 2018 draft by the Islanders, and shortly ahead of his 10th birthday Oliver Wahlstrom was briefly a hockey legend.
