No. Not at all. There's no "or else".
They're only accountable to themselves. They have to look in the mirror and know they did do all of the right things (and none of the things that tripped them up before) to achieve this lofty goal they're setting for themselves.
They can do it.
They need to critically self-evaluate what they've done right, and wrong, to put themselves into this position (pre-season favorite and loaded for bear) and then go out there and do it as far as they can. This team is better than 4-7-1 at home in a half. This team is better than two disappointing showings in national semi-finals. They have the experience; they've made a (good) choice and they get to prove what they've learned and why they're better.
If they run into a better team or hot goaltender and lose, so be it, knowing that's the only reason anyone stopped them.
