Every team that scored first in a game seven of the 2021 playoffs won that game, and the team that has scored first in games sevens has an overall record of 138-46 all-time in NHL history.
Boston Bruins forward Taylor Hall was this close to opening the score this evening against the Carolina Hurricanes:
Hurricanes' goaltender Antti Raanta made a spectacular sliding save to keep the score at 0-0. Of course, Carolina would open the scoring not too long after, and that's currently where things sit after the first period.
The Hurricanes also have 3:03 remaining on a Hall double minor for high sticking right after Carolina made it 1-0.
