What changed between games 1,2 and games 3,4?

Canucks aren't forechecking near as much?
Boston's more physical?
Injuries?
Thomas is in the zone
Luongo's losing confidence
Canucks defense can't clear the rebounds
Boston's going glove side on every shot

Thoughts?

Going to have to record the remaining games as I'm going on vacation and prob won't be keeping up as I'll be on the beach drinking cold beers, eating oysters, and and breathing. That's about it. If the games are on I prob won't notice them as the TV will probably stay off.
