I'd take the Rangers and/or Ottawa.
The Islanders are a team that is young, have Tavares and Nabakov whom Sid/Geno have never scored on....plus we all know other history involving the stale Islanders team.
Ottawa still looked mediocre even with Karlsson...He's not hard to figure out. Put bodies on him and physically wear him out of the play. He can only wear 170lb?
Rangers would concern me if they could score. They have Fat Nash whom has never seen playoffs so he really doesn't know what it takes, but Lundqvist could get hot as he sits in his crease, allowing his extra padding to make the saves.. But the Pens have never had a problem beating Henrik Lundqvist.....no matter how hot he's been.
It really doesn't matter though... If these teams scare you in the first round, they surely could past their opponents and still end up playing the Pens in the Second/Third round.. I say, Bring it on whomever!!!! We'll beat you.
