Game 1: This was a close call for the Canucks. Both goalies played well.
Game 2: Luongo certainly was the difference.
Game 3: Won without a miraculous performance from Luongo.
Game 4: Didn't expect to win in 4, and I think the Canucks need the rest.
I'm not normally one to break up a season, but since Sundin has been on the team and Luongo has been healthy the Canucks have averaged 3.2 GF/game. The Canucks have also won 64% of their games since then and if you separate the games that were against playoff teams the offense goes way up: 3.6 GF/game.
I noticed the regular season games were high scoring, however considering St. Louis' anemic scoring and Luongo's goaltending I would think this series could be quite low scoring.
This all said: even if you ignore their recent history, the Canucks are +30 on the season and St. Louis is +0.
