If "It shows we can stay with these guys now" is important for them, it also "shows that we can't take them for granted" which is just as important for us.
8 blowouts and then you meet them in the 1st round, you could have woken up with a 2-0 deficit.....now we know that they won't be as easy to beat and we'll be ready.
That game was just as important to us then for them.
Yep, remember the Canes series in 2006? They had beaten us like 8-2,7-3,8-2 and then came into the playoffs and we took a 2-0 series lead and probably if Koivu wouldn't have been injured we would have won that series.
