"We were pretty motivated," stated Gallagher, following the 3-0 victory. "This was a lot of guys' first taste of the Montreal-Boston rivalry. It's always fun coming into this building."
Gallagher has put up more points (7g - 13a) against the Bruins than any other team since debuting in the NHL ranks back in 2012-13.
And, 13 of those points (5g - 8a) have come while the Canadiens were on the road in Massachusetts for contests at both TD Garden and the 2016 Winter Classic at Gillette Stadium in Foxborough.
