The sheen is going to come off the Bruins.
There are quite a few guys playing way over their heads right now. The entire 4th line, the 3rd pairng...i know they can skate, if San Jose gets through they have the roster to beat the Bruins.
I can't see the line of Nordstrom, Acciari, and Kuraly continuing to lead the team in scoring the way they did in games 1-3.
The Blues will have a harder time matching up, they will have the same problems as the 'canes with the B's overall depth.
The 3rd line with Johannsson and Coyle is quite good though and will be a problem for the Blues.
