Aaron Dell started in goal for the Sabres and allowed four goals on 22 shots before being replaced by Tokarski to begin the second period. Coach Don Granato had given the start to Dell in part as a mental reset for Tokarski, who had been pulled from his last two starts.
Despite their high volume of shots during the back half of the opening period, the Bruins generated just two high-danger chances according to counts by Natural Stat Trick. The final count was 5-3 in favor of Boston.
"Never have I been comfortable as a coach trying to say it's a goaltending thing," Granato said. "Even if at times you thought maybe that could've been a save, you still look at the things that led to that and work to improve those.
"So, if that's the case and it was a goal that we didn't like, there's other things that we can turn our attention that are within our control to become better at, and we have that opportunity to become better at it. So, this little stretch is exposing us to things that we need to target and become better at, and we will. We will become better at it going through this."
Patrice Bergeron pounced on a rebound after a scramble in the crease to ignite the Boston run. Charlie Coyle tallied the winner just 51 seconds later, sending a shot from the right faceoff circle over the shoulder of Dell and in off the crossbar.
David Pastrnak was responsible for goal No. 3, a one-timer from the left faceoff circle. Mike Reilly completed the barrage when a shot from the point deflected off net-front traffic and onto the defenseman's stick to the left of the net.
The stretch proved to be enough for the Bruins, who entered the night 7-0-0 when leading after the first period. The Sabres made a push during a 14-shot second period but were outshot 18-3 in the third. Taylor Hall scored the final goal for Boston on a power play with 4:34 remaining.
