If the Bruins were tired two nights after the Maple Leafs brought them to the brink of elimination, they didn't show it.
Following Saturday night's overtime victory over Toronto in Game 7 of the first round, the B's traveled to Florida to take on the Panthers, earning a 5-1 win to start the next series Monday night.
Both teams were scoreless in the first period before Matthew Tkachuk got Florida on the board nearly 12 minutes into the second period.
The Bruins responded with a flurry of goals late in the second, from Morgan Geekie, Mason Lohrei and new father Brandon Carlo.
