Quick tally shows that so far, through all their series, the Senators have been outscored 47 - 45.

This continues their performance through the year...

It also shows that a while a lot of stats are generally indicative of performance/outcome (Corsi, possession, face-off wins, etc.) they are not always true, or indicative of outcome...

IF (and this is a BIG if) they were to win the Cup, it would be interesting to see how far back you have to go to find a team that won it, but were out-scored during the playoffs..
