Truly, the top 9 has never looked as good as it does right now since at least the Sundin/Mogilny teams, and I can't even remember who we had on the third line back then, just that we were pretty deep.
And Gregor and McMann are more than fine for me on the fourth line too. If we can get a better guy, great, but as wingers, I think they're about as good as you're going to do without paying third line money for someone.
The big glaring weak link on the team is Kampf, and sadly they're not going to do anything about it, and Keefe will play him more than he has any reason to do. Only injury will move him out. And heaven forbid Reaves heals up and moves back in.
