That's why they call them 'special'
Gabe Desjardins has cranked a few more numbers over on his site, and from these we can now determine which teams spend the most time on the power play, the penalty kill and even strength.
Obviously, if you're a coach, you're going to want your team on the power play more than the penalty kill because, well, goals don't usually go in the wrong net when you're up a man. (It's a little more complicated than that, so keep reading.) The average NHL game this season has broken down with 45 minutes of even-strength play, and 15 minutes on special teams, 7.5 on the power play for each side.
Those figures vary for each team, with Columbus spending the highest percentage of its minutes up a man (15.4% or 9:15/G) and Boston the lowest (10.2% or 6:05/G), which means the Blue Jackets have played more than three minutes a game more on the power play than the Bruins through the first dozen games.
Toronto, meanwhile, has spent the most time killing penalties (a whopping 16%), with Edmonton coming in at the low end at (10.3%) — about a 3:25 difference per game.
But here's what what you really came to see (figures from before Sunday games):
What complicates all of this is that part of the reason teams spend a lot of time on the penalty kill is the fact they don't get scored on and therefore have more unbroken two minute chunks. Likewise, teams that have had difficulty scoring on the power play are more likely to be out there longer. (Columbus is a good example here, as they've got the league's top penalty kill but are middle of the pack when it comes to shorthanded situations. Because they've rarely been scored on, however, they're generally killing a full two minutes, which bumps them up in the 'percentage of time spent on the penalty kill' rankings.)
All that makes it more difficult to make blanket statements about New Jersey being a more "disciplined" team than the Red Wings — although even the NHL's own generic stats would bear that out.
The Behind The Net numbers also give you an idea of which teams play in more penalty filled games, with Columbus, Buffalo and Toronto all playing less than 72% of their games at even strength this season (~43 minutes). On the flip side, 79.4% of Boston's games have been at even strength, a difference of about five minutes a game.
There's a lot of data here I haven't even had a chance to look at; my guess is there's much more to be mined from these figures than what I've got here.
