Nashville, will be the best for a long time, the fact they nearly beat Chicago this year with that forwards corps is amazing.
Their defense is not only mobile and offensive, they are physical and pretty balanced. IMO they have the best D in the league, and they still have 3-4 guys who could all become top 4. Franson, Blum, Ellis, Roussell... Scary^^.
If Cowen, Rundblad and Wiercioch pan out as they all should be though, Ottawa could be right there, because that's a top 4, with Karlsson, that would be pretty balanced as well. Cowen the mobile shut-down guy, Karlsson the pure offense and the other 2 in between.
As for LA, if Teubert becomes as good as Seasbrook, I would cry if I were in that division. Don't forget Jack Johnson, he may be a special character, but he is still very good.
St-Louis is gonna be amazing too. Ian Cole and Polak with the Pietro and Johnson is at least top 5.
Luckily for us, all of them are in the West.
I like Phoenix too but I think they need one mean guy.
