Before everybody gets to where they're going for Thanksgiving (US edition), we can give some thought to the annual Thanksgiving Standings canard. In summary, any team that's 4 points or more removed from the playoffs at US Thanksgiving is basically doomed. Given the general malaise/parity in the league this year, that's not much of a list really.
In the East, you're only talking about the Sabres and Leafs(!). The West has a little more separation, and their drop zone list includes the Blues, Canucks, Flames and Predators. Obviously the Leafs are the feature act here. Most expected them to take a bit of a step back, but their defense and goaltending have taken a dive to the point where they seem to be unintentionally tanking. You could make a case for St Louis also being a surprise doldrum dweller. Jim Montgomery really seemed to have righted their ship last season and they didn't make substantial roster changes, but their goaltending has tanked and it shows. That minus 24 goal diff is ugly, with only the sad sack Preds keeping it out of last place. Calgary is a mild surprise here also, but I didn't think they were any good last season either. Now, with the new goalie smell worn off of young Dustin Wolf, they look like a typical one line NHL team ... which is what they have been for a couple of years.
So, who is a candidate to get their mess together out of that group? Toronto, obviously, but they do look well and truly broken right now. I'd also say St Louis, but that goaltending has to improve before I start believing in their chances.
