Even after some good moves at the deadline, I think it's safe to say that the Caps are not Cup favourites. Moreover, there are some superbly talented teams this year who have a very strong shot.
The same could have been said of last year's Flyers. They made it into the playoffs on a shootout win in the last game of the season, their goaltending wasn't exactly stellar, and there were teams far more likely to be successful. Nevertheless, they made it to the Cup Finals and took the Blackhawks to overtime of Game 6. Hell, they played a good enough series that with different bounces of the puck, the series could still probably have gone either way.
What explains their success? Were they a strongly talented team which, based solely on their play down the stretch, may have deserved a higher seed? Were they just defensively strong enough to hold off their opponents? Moreover, what changes over the offseason explain their ascendency from regular-season mediocrity last year to dominance this year?
Most importantly, how analogous may they be to the Caps of this year?
