The Blues have been down this path before. They were down 3-2 in the playoffs against the Stars last season. St. Louis rebounded to win that series on its way to capturing the Stanley Cup.
Maybe the Canucks can take out the Blues. But I don't see it happening in this Game 6. 
The Blues are kicking themselves for blowing a 3-1 second period lead in a 4-3 loss to the Canucks on Wednesday. 
Outstanding goaltending by Jacob Markstrom has been a huge key for Vancouver. The Blues have fired an average of nearly 43 shots a game during the last three games. I don't see the Canucks being able to keep up and Markstrom is due to start wearing down.
