Yea, down 3-1 is hell, but it's one game at a time, the Celtics have shown clearly that they can play and beat this Heat team, and the Celtics, by all accounts, should have won last nights game. Some crucial late game mistakes really caused the Celtics to pretty much beat themselves. That 3 on 1 fast break... it still hurts a lot.
Either way, all it takes is the Celtics coming out and playing their game in the next 2 games of this series, and coming away with wins. Staring at the 3-1 hole, it would be easy to just pack it in thinking it's all over, but this team is absolutely capable of winning this series, and they should be very aware of this fact. They don't need to win 3 games all at once. They just need to win one.
As far as the Celtics are concerned, this might as well be a game 1, and they want to start off with a win. Then, after going 1-0, you obviously want to go for the 2-0. After that, they go for the 3-0 advantage in game 7. This is how this Celtics team has to view this series.
This Heat team isn't all that difference from the Heat team we beat 3 times in a row early in the season. Some might feel that they are, but the Heat could have won either of those three games, we just finished the games properly. This myth that Heat couldn't win close games, has always been just that, a myth.
The Celtics can win this series. Just take one in Miami, come back home and win there, then go for broke in Game 7. One game at a time is all it takes. All the pressure is now on Miami to close this series out. Let's allow a bit of doubt to creep in.
The Heat being up 3-1 doesn't make them any more likely to win game 5, or even game 6 and 7.
