The first phase of this partnership [between the NHL and SAP] debuted Friday. Shot attempts, also known as Corsi, and unblocked shot attempts, also known as Fenwick, have been staples of the advanced-statistics community and are now, along with dozens of variations, on

Other new statistics include penalties drawn and penalties taken, primary and secondary assists, and zone starts. Another advanced metric is SPSV%, also known as PDO, which is combined on-ice shooting percentage and on-ice save percentage and is used as a measure of good fortune enjoyed by an individual player or team.

Part of the initial phase includes the decision to use different names for the statistics that have been known as Corsi, Fenwick and PDO.

More to Come

The second phase, expected to launch by the start of the 2015 Stanley Cup Playoffs in April, will include new ways to visualize all of the data on the website. It will feature advanced filtering, which will make it possible to sort and aggregate data from individual games or across multiple seasons.


The third phase, expected to launch by the start of the 2015-16 NHL season in October, will include new metrics developed by SAP. A final phase will include the digitization of historical stats all the way back to League’s inception in 1917 and a spoken-language search function.
