For one, it's a considerable improvement (from last game) against a team that is considered (by a few hockey analysts here in Canada), to be the Gold medal favourites. Finland has by far the best defensive core. Not just this year, but the best I've seen any team have in a while. Don't forget that Finland also had 7 power plays in that game.
In pre-tournament, I'm ok with it yes.
I think with a few adjustments and some luck, Czechs can be competitive. As you saw, they moved Zadina to second line with Necas. Who knows what's next. But you can tell that Pesan is not blind like other coaches.
There's been many years where Top teams play terrible in pre-season and everyone thought they'd suck. Then they came out strong come real tournament. Not saying that's the case with Czechs. But I think we're judging too much on these games. You guys might be right, but it's simply too early. Let's see what happens on the 26th and judge from there.
