I don't really expect them to score that much more than last year unless they add a significant proven NHL forward or two.
Past the three centers, this is basically an AHL caliber group of forwards pretending to be an NHL team.
That doesn't work in the NHL. You can't pretend your way through 82 NHL games, eventually (probably sooner than later) you will get exposed.
Your best bet is maybe that Tippett plays some kind of trap system, but that probably goes down the tubes real quick if Klefbom suffers his annual injury.
If anything too I think the book is fully out on the Oilers too, every team scouts us hard because of McDavid, and every team knows exactly how to play us ... you pick on/shut down lines 2/3/4 and forecheck the heck out of the D group until they start making mistakes and then go to town on the goalie.
