One of the fun things you can do when your team changes coaches about a quarter way through the season is compare how the new guy is performing compared to who is replacing. The general consensus among Carolina fans is that new coach Kirk Muller is doing a fantastic job and is more suited for this team than Paul Maurice. Despite those claims, the Hurricanes performance under Muller hasn't changed much compared to how they played under Maurice. They are controlling possession at about the same rate and are only roughly a win better under Muller, and that extra win likely came from Cam Ward standing on his head for all of January.
However, I think it is safe to say that the Hurricanes main issue is talent and not coaching because you can only do so much with players like Jiri Tlusty and Alexei Ponikarovsky in your top-six and a defense corps where Tim Gleason is your best player. Muller can't control who he has on the team but what he can do is control how he uses them. With the help of Time On Ice's "team faceoff" option, we can look at how the Hurricanes two coaches this year have been using their players by seeing how often they deploy them in the offensive and defensive zone respectively. You will see some huge differences between Muller and Maurice's strategies.
