NEW YORK - Crunch the numbers, ride the waves of momentum, and then try to guess if the Washington Capitals or New York Rangers will survive another Game 7 and move on to the Eastern Conference finals.

Hockey analysts will make very compelling arguments - and leave anyone who is listening believing that both teams can't lose the win-or-go-home matchup on Saturday night at Madison Square Garden.

Ah yes, Madison Square Garden, the famed arena in which the host Rangers are 4-0 in Game 7s. It is also the place where the Rangers pulled out a Game 5 win in this series by scoring a power-play goal with 7.6 seconds left in regulation, and then another less than 2 minutes into overtime, turning what appeared to be a sure loss into one of the most electrifying victories in club history.

You know, the tide-turning win that the Capitals would never be able to bounce back from - even though they were heading home for Game 6. It didn't quite work out that way, and now it's the Rangers who will fight to make sure there is no carry-over in the other direction for Game 7.

"We can't let it," Rangers captain Ryan Callahan said. "We have to put this one behind us. We have to go in Saturday ready to play."

Whoever prevails will face the well-rested New Jersey Devils with a trip to the Stanley Cup finals on the line.
