I'm the opposite. Trotz has better goaltending and a veteran forward group that doesn't have any real rookies or AHL/NHL tweeners. Canes have the edge on defense, but overall, the Isles have a much deeper forward group IMO. While we're icing guys like McKegg, Foegele, Maenalanen, Wallmark to fill out our bottom 6 - (rookies because we had no choice), they have veteran NHLrs like Komarov, Cizikas, Clutterbuk, Martin and Kuhnhakl (and even Ladd when not injured).
What I give Trotz a lot of credit for though, is getting their talent (particularly their higher end forwards) to buy in to the defensive minded game. I wouldn't argue RBA over Trotz, but I do think that NYI team is deeper at forward than the Canes are.
