As lopsided as the end result might be, I do think experiencing playoff hockey is important for the younger players (McMichael,Lapierre,Strome,Alexeyev etc.). There will be a day when those guys find themselves back in the playoffs and use the sting of this one as fuel for a better fate.
It does feel like the Rangers are coasting a bit, but I imagine they are still shellshocked from running out of GAS in the ECF two seasons ago. They have paced themselves WAY better this season (a big reason why I think they won the Presidents trophy) and have seemed to find the balance of pushing for the needed/go-ahead goal and then just going through the motions.
I think they know there is a battle on the horizon in round 2.........
