The Avalanche must have an amazing team this year, I haven't watched any of their games. But a couple of great stats, they have taken more shots per game than any team in the league and also allowed the fewest shots per game than any team. They have scored more goals per game than any team in the league (Actually tied with Tampa) and allowed the fewest goals per game than any team in the league.
It is hard to tell because their division is a weaker one in the league. The West is effectively a mirror of the Central. Tampa and Vegas are the powerhouses but have only been mediocre against the good teams. Carolina and Colorado are promising but haven't been able to get over the hump. They have done a bit better against the good teams though. Minnesota and Florida are punching above their weight and will make the first round tough for whoever is 2nd but likely bows out in the first round. Then the rest of the division is bad (since St. Louis has looked brutal in the West more often than not) and where the top teams are really racking up their points.
It'll be interesting to see come the playoffs when these teams are constantly going up against good teams. People say the North is weak but we have one less team and we still have to go up against 3 teams that are legitimately good on any given night in EDM, MTL, and WPG. The East is the only one who can really match that kind of depth in their division (but they also have free points in BUF). The other two divisions only have to play 2 harder teams and get 5 teams who can barely keeping their heads above water.
If the Leafs perform well against Winnipeg the next couple of games, we are the only team with a legitimately good record against all of the tough teams in our division and ironically would have our worst record against Ottawa. Colorado would be similar, but they are only shooting .500 against Vegas right now, and are also struggling against Anaheim and STL.
