2. EASTERN CONFERENCE FINAL, May 27, 1994, NEW YORK RANGERS VS. NEW JERSEY DEVILS, Madison Square Garden
There wouldn't have been a '94 Stanley Cup for New York without this thrilling 2-1 double-overtime win over the Devils. Long after New Jersey's Valeri Zelepukin had scored with 7.7 seconds left in regulation to send the game into overtime, the Rangers' Stephane Matteau scored a wraparound goal that set up the Rangers' date with Lord Stanley.
3. LEAGUE SEMIFINALS, April 2, 1939, BOSTON BRUINS VS. NEW YORK RANGERS, Boston Garden
The first best-of-seven semifinal format in league history wasn't decided until after 48 minutes of overtime, when a goal by Mel Hill, a winger who had scored only 10 of them in the regular season, gave the Bruins a 2-1 victory. Hill had scored two other overtime goals in the series and will be forever remembered in Boston as Sudden Death.
4. WALES CONFERENCE FINAL, May 10, 1979, MONTREAL CANADIENS VS. BOSTON BRUINS, Montreal Forum

5. STANLEY CUP FINAL, April 23, 1950, DETROIT RED WINGS VS. NEW YORK RANGERS, The Olympia, Detroit
The underdog Rangers, who had to "host" Games 1 and 2 in Toronto because the circus was encamped in Madison Square Garden, took leads of 2-0 and 3-2 in Game 7, but couldn't capitalize on several late scoring opportunities. A goal in the second overtime by obscure winger Pete Babando gave the favored Red Wings a 4-3 victory.
