yup... Price will need to be at his best. Outdueled Helleybuck, and will need to be even more definitively better than fleury.
that "punishing" defense got absolutely shell shocked by Toronto. Vegas is both just as dangerous offensively and far more imposing physically. Much more difficult match-up for our lumbering group that defaulted to icing the puck religiously to stem the pressure Toronto was able to put on.
I didn't watch much of Minnesota this year, so can't comment on their "structure"... though for how much better they did despite a roster that didn't look like a playoff-worthy team and had several young guys stepping in, i'd be surprised to know that they didn't have a tight, structured approach.
Your assessment of COlorado as "less structured" i don't think is accurate. A team doesn't post the second fewest GA, in front of a goalie like Grubauer, without playing pretty structured hockey. They have the horses to take more risks and open things up, sure, but that doesn't mean they weren't structured. They dismantled the blues easily, giving up less than 2 goals/game and holding them to 27 shots/game. In game 5 & 6, they held vegas to 23 & 25 shots against and still lost. Vegas is just that good.
