The east will probably be a bloodbath again... Florida, New Jersey, Rags, and Carolina all look strong. Carolina will probably do their yearly no show. The next group down in the east are the Leafs, Bruins, Bolts group. Where the Bolts are probably the most likely to slip from there (I'm not sure if they even make the playoffs). Neither of the other teams look likely to move up. From the West, Stars and Oilers are above the rest with the next group of Avs, Vegas, and Vancouver. Vancouver probably the best chance to move up, and Vegas a very good chance to move down. Nashville is probably the team that can elevate to join that group. They aren't young, but they brought in talent.
The top 5 has to be some ranking of Florida, NYR, New Jersey, Dallas and Edmonton. Vancouver is the dark horse in the West. They need some health in net and they need to grab a top 4D... but they have the most aggressive GM in the league and assets to spare. Carolina will top a lot of lists, but I just don't think they have it.
