I think it was more Anaheim playing poorly in the first, and then going back to their game the rest of the game. Ottawa lost the game last night when they couldn't score more than one in the first.
In the entire third, Ottawa didn't get one good quality scoring chance due to the Ducks' tight defensive system and SMART play.
Give credit where credit is due to the Ducks. Using a tennis analogy, Ottawa's errors aren't all unforced errors. The aggressive Ducks forecheck is making Ottawa play sloppy, and Ottawa's leaders and best players haven't showed the composure that Anaheim's have shown.
Anaheim's been the better team in this series and deserve to win. Ottawa and its fans should take pride in making it this far and being the Eastern champs but no one can say they deserve to win the Cup. They've been outmatched.
I don't think Ottawa needs to panic and there's no reason to break up the core. I wouldn't mind seeing Redden go in favor of a couple of cheaper D-men for depth (especially how Preissing could walk as a UFA). If after next season (when Spezza, Heatley, Redden, Fisher are FA's) they don't win, that's the time to retool.
