Matt Cane, an analytical hockey writer who publishes his work on a number of different platforms like Hockey Prospectus, Hockey Plus Plus and Hockey Graphs published a series of tweets last night that used data visuals to highlight some data that he has been capturing and working with.
Essentially he is using an X-Y graph to plot how often NHL defencemen give up shot attempts per 60 minutes of even strength hockey. Instead of just being a raw figure like Corsi (or just total shot attempts), Cane has pared Corsi down into two different metrics — initial shot attempts against per 60 minutes of 5v5 hockey and follow-up shot attempts against per 60 minutes of 5v5 hockey.
