The Rangers lack what they have lacked for a long time now, grit and toughness. I think they are better equipped this year on that front with Cuylle, Trocheck, and Wheeler on the 3rd line, instead of the finesse and skill of the Kid line, but it is still a concern for this team.
The 4th line is what it is. I actually think it is better this year than it has been for a while. Goodrow is a solid 4th line guy, and a mix of Bonino, Vesey, and Pitlick is certainly not great, but better than it has been. Maybe at some point Othmann comes up, and Wheeler moves to the 4th line with Goodrow. That would be a very nice base for a 4th line (think Perry who has been on the TB 4th line the past few seasons), if Othmann proves he is ready after a few weeks/month in the AHL to get acclimated to professional hockey over here.
