For the same reason that if we somehow snuck into the dance, whoever we ended up playing should not be too overconfident vs us seeing we could be a very dangerous out.
I kind of feel similar about the Leafs. This may sound nuts but if the Leafs sneak in to the playoffs, whoever they face better not be overconfident versus them either seeing as Jekyle and Hyde as they are, the'd be a very dangerous team to have to play come playoff time.
Wouldn't shock me in the least that in a year when most wouldn't expect the Leafs to go on a run, that this is the year they will pull of an upset or two.
