Putting up 14 shots at home is never going to help you with a metric dependent on shot attempts. So while last night's game was particularly poor and not really representative, the trend of the graph is clear.
Replace an Erik Karlsson with an Eric Gryba and your team is going to have the puck a lot less.
I'm not predicting doom and gloom for the team, they're comfortably in a playoff position and their schedule down the stretch isn't exactly filled with world beaters. That MacLean has held things together with this roster and continued to bank points is a huge credit to him, and the goaltending.
But once they're in the postseason I'd certainly like their chances better if they were the team more than not putting up the most shots. A healthy Spezza will help in this department (obvious statement is obvious), so we just have to hope he's Spezza when he returns...and not something else. I'd be cool with similar form to Havlat after he missed the bulk of the 05/06 season.
Just curious: with all these possession-based statistics out there, I haven't seen one that tracks literal possession of the puck; they all seem to infer possession through shots/chances taken/against while on ice. How about coming up with a figure like TOI, except TOP (time of possession), to track how often a particular player or team has the puck during a game? I don't see why that would be harder to track than TOI is. It might yield even more useful information, especially if broken down by zone and combined with the shots/chances data.
@Mothballsuitor The NHL used to track and publish just that. http://www.nhl.com/scores/htmlreports/20012002/GS020666.HTM
For some reason they stopped. But shots and shot attempts are a good proxy. http://vhockey.blogspot.ca/2008/08/zone-time.html
