Top 10, for sure, but top 3 is a bit of a stretch.
I think potentially, they can crack the top 5 but as I see it now they have a tough time fitting in there. Hawks, Pens, Caps, Flyers and as much as people don't want to hear it, I think the Wings fit in there too (or the Sharks). Dallas could be in there, but I'm not sure they are deep enough to withstand a long season -- same opinion on the Rangers. Time will tell on those two..
I think Torontos honeymoon is over, but I think they can still make the playoffs, Edmonton and Minnesota will keep falling and probably end up as a 7th or 8th seed by the end of the year. Detroit will keep pushing (I think probably into the top 5, if not definitely top 10), as will the Bruins and Canucks. Buffalo will have a chance of cracking the top 5 even if Miller is out. Phoenix, I'm not sure, they seem like a wild card to me. Sharks will be a consistent team, whether or not they are consistent enough for the top 5 is to be determined.
Nashville will be consistent as well, but not enough for the top 5. Florida has a great chance at a playoff push, LA has the potential to be a top 5 team. Vancouver won't be a top 5 team even in the Western Conference let alone the league, but still will probably make the playoffs. Tampa is a borderline team, New Jersey is borderline but I can't see them making too much noise. Anaheim has underachieved, but still can turn things around with a nice win streak. The rest aren't even worth talking about.
It's still too early to predict, but I tend to lean towards teams that have had success for many years now than just throwing a team like the Rangers in the top 5. There's 82 games for a reason.
