*This is all coming from a Rangers fan*
Why The Rangers Will Win: There is 2 reason why the Rangers will win. First off, its the King, Henrik Lundqvist. He has been a top goalie all year and even career long. He has also had postseason and Olympic success. He works well under pressure and can shutout any opponent (he has 2 SO against the Capitals already). The other reason is the teams ability to overcome adversity and play as a team. This team is a very physical team and there "big guy" Brandon Prust will go up against anyone if it helps spark the team. The Rangers penalty killing isn't only good but they also have the ability to score the short-handed goal.
Why The Capitals Will Win: This team can lit up the scoreboard on any given night and with Mike Green coming back, it just makes them more lethal. He doesn't help the team too much defensively, but offensively, he really adds another aspect.
Why The Rangers Will Lose: They just won't score enough and there young defensive corps will falter. The King will also struggle due to fatigue after playing 26 straight games.
Why The Capitals Will Lose: The pressure. This team was the best team in the East again. last year they succumbed and lost to the Canadiens after leading 3 games to 1. Another reason is that Ovi will continue to struggle to score vs. the Rangers as he has no goals in the 4 games that have happened in the regular season.
My Prediction: I think the regular season told a lot. I'll give this to the Rangers in 4 games. (Before you all attack me read the note on the top of this post). I think they have enough to win and the fact the Capitals haven't shown any good success against the Rangers this year. Also on a side note, the Rangers were up 3 games to 1 in 2009 but that was a long time ago. Neither team is the same.
