The second round is new, uncharted territory for the Calgary Flames. It would be in general, but it's especially new for this team, what with a heavy contingent of rookies and all.
The Anaheim Ducks are very much not the Vancouver Canucks, though. The Canucks were roughly on the Flames' level. The Ducks were the best team in the entire conference, and only got better after the trade deadline.
It's also the playoffs, and with a well-rested, eager Ducks team against an inexperienced, overachieving Flames squad... Well... It would be a long night.
