Given that The Blues shut down Kane & Toews, and Benn & Spezza, I think they can do the same to Thornton, Marleau & Couture and Crosby, Malkin & Kessel. The only question is whether or not The Blues will come to play at the start of each game, not let down when the bounces don't go their way, and want it badly enough to do everything it takes to win, for the 3rd and 4th series.
I can't imagine The Blues losing to Nashville. I can see them losing to The Sharks, but I expect them to win that series. The Cop Finals would be a toss-up against The Pens, or The Bolts (IF Stamkos is back, playing decently), if NOT I expect Pittsburgh to beat them, and Rhe Blues not face them.
