There are far more data collection tools available for analyzing NHL shot data than we have in college hockey. The technology is there, but it’s a lack of manpower more than anything else. Publishing shot attempt heat maps for every team in a conference would be a nightmare and require hours of video analysis.
Ed. Note — For VIP members, I’ll analyze these charts more in an upcoming VIP blog post …
But there are other ways to analyze shot quality both for and against, with the best indicator (for college hockey) being how many shot attempts actually get through and land on the goaltender. The first chart (below) shows SOG percentage for every team in the league at even strength (blue) and on the power play (red). What surprised me is that the league average is just about 55 percent in both situations. I expected the league average to be higher on the power play, but it isn’t. That’s likely due to teams attempting more shots per minute on the power play, and less of them hitting the goaltender (more blocks, shots wide, etc.). The league average at even strength is 55.9 percent and the league average on the power play is 54.02 percent, which is indicated by the green horizontal line.
The chart below here are SOG percentages against. As you’ll see below, BU, Massachusetts and UMass Lowell both are excellent on this chart, allowing much fewer shots on goal (per attempt) than the league average.
Lastly, the chart below is SOG percentage against on the penalty kill, where you’ll see that, BC, UMass Lowell and Providence have the best PK units in the league in this category, with the league average falling at 46% of shot attempts against hitting the net on the PK.
