Two things you have to remember, in regards to the Rangers playoff runs. 1) if they win game one, then they never win game two. 2) The Rangers never blow anyone out in the playoffs - only they get blown out - they only win tight, and close games.
Number 2 hasn't be true for a long long time.
The Rangers haven't been blown out all playoffs until now, and last blowout was a few years ago, nothing I remember from last year. OTOH the Rangers blew out Montreal badly in game 1.
Otherwise every other game was close or relatively close.
