I'm more surprised at how we have gelled than how the Flames are playing. They are a continuation of last years steps forward while we are a total rebound. Their speed makes them dangerous, and that can make for exciting hockey. Next Flames Canucks game should be a good one.
^ They are fast because they have a bunch of young energetic forwards that have boosted their team speed and as you already said they have 3 quality mobile, puck moving, offensive d-men.
^And like us, they are playing confident hockey right now. If their D can sustain what they are doing right now, and the young guys keep the pace up for the season they could make a playoff splash. Goaltending might be a question mark if all else goes well.
