No doubt? The Bruins are the most complete team the Canes have faced. On the season, WSH was better overall offensively than the Bruins and Isles were better overall defensively, but Boston was pretty good in both categories and had better balance.
Regular season:
GF: Caps 5th, Bos 11th, Car 16th, NYI 22nd
GA: NYI 1st, Bos 3rd, Car 8th, WSH 17th
Canes stunk during Oct-Dec though and finally put it together in late Dec (and added Nino in Jan).
Since Jan 1:
GF: Car 2nd, Bos 6th, Wsh 11th, NYI 24th
GA: NYI 1st, Bos 7th, Car 11th, WSH 20th
IMO, Boston is the most complete team of all of these teams when looking at offense, defense, depth, goaltending, special teams, plus they have home ice advantage.
I'm not saying the Canes can't win, but saying "no doubt we are the better team" is a bit of a stretch to me.
