Ducks, Sharks, Blackhawks, and Blue Jackets are all horrific and thus should be able to accumulate good prospects over the next few seasons giving them a shot of escaping the basement quickly.
Sabres, Sens, Habs, Coyotes, and Flames are more middling, and are more likely to end up in perpetual mediocrity in my opinion.
I think the Sens and Sabres have the best collection of talent in this group in my opinion, and I think they'll make it at some point with their cores.
It's between the Habs, Coyotes, and Flames for me. Flames are older, but tend to be somewhat competitive and may sneak in. Habs are okay, but lack high end talent in my opinion. Coyotes are just.. the Coyotes, a team who can never seem to get out of their own way.
