You caught me when I'm excited about the season starting and have some downtime at work while I'm waiting on something, so this got long. Flyers to come in a separate post.
All three have a good chance of heartache, and none would be considered frontrunning at this point. The Blue Jackets have the most near-term hope and are certainly the most likely to make the playoffs, Flyers and Hurricanes are both rebuilding but have some young guys with a lot of potential.
Blue Jackets - hired a new GM that seems like a smart dude, and made waves because he is the first European GM (The NHL is weird about Europeans.) (Plus he has a killer name - Jarmo Kekäläinen.) They don't have any really hateable players, though Jack Johnson tends to be the target of the stats crowd. Took advantage of Chicago's tight cap situation and got Brandon Saad this off season, which is a bit of a coup because it's not easy to get young talent outside of the draft. Their goalie is a former Vezina winner and is adorable. They have a prospect named Boone Jenner. They shoot a cannon when they score a goal, which could be a plus or a minus. (It's loud.) Young team, which is fun. OH, and Scott Hartnell is the absolute best. (Some rival fans hate him, mainly from his time as a Flyer, but they are wrong.)

Hurricanes - plenty of fans here, so they can probably sell you better than I can. They accepted that they'd have to rebuild last year, but they still have some big contracts on the books, so they're kind of in transition. The coach they hired appears to be good, and they convinced him to take their opening instead of the Penguins, which was funny. They just signed goalie Eddie Lack to an extension, and he's good at Twitter (possibly at least in part because he was mentored by the king of NHL twitter, Roberto Luongo.) It would involve cheering for Jeff Skinner, which could be considered a good thing (he's been described as the Justin Beiber of hockey (wait, is that a good thing?), and he has some sweet moves since he has a background in figure skating) or a bad thing (see:
