The Tampa Bay Lightning have been here before.
Trailing 3-2 in their first-round series to the Detroit Red Wings, the Lightning quickly put a 4-0 loss behind them by pulling off a Game 6 road win and, two nights later, a Game 7 shutout win at home. They also handed the New York Rangers their first ever Game 7 loss at Madison Square Garden, where they'd previously been 7-0, in the Eastern Conference Final with yet another impressive shutout victory.
So this isn't anything new to the Lightning.
The only difference is, this is the Stanley Cup Final, a place they haven't been since 2004 and somewhere the Blackhawks have been three times in the last six years.
