No teams in the NBA have ever come back from a 3-o series deficit in any NBA 7 game series including the Finals.
The 2001 New York Yankees
Sharks
In hockey, The Boston Brewens were losing 4 to 1, and made a come back and won the game.I hope this helps.
Montreal Canadiens came back from a 3-1 deficit in 2010
miami heat 2006 vs dallas
No one has completed this feat in NBA history yet
You can add one more to that list however many it is, because the Miami Heat are about to do it
Most of the teams who have successfully rallied from a 3-1 hole (six of the eight) enjoyed homecourt advantage.
No 30 out of 30 teams that had a 3-1 lead in the finals won the championship.
0. The only hockey team to come back 3 - 0 was the Philadelphia Flyers who came back to beat the Boston Bruins in the 2010 Stanley Cup Championship, and they were the 7th seed.
Only one! The Knicks vs Heat, game four, May, 6 2012. Against all odds, the Knicks beat the Heat 89-87 The Knicks only won a single game after being down 3-0. They didn't come back and win the series.
