There is a great deal of evidence showing that shot metrics, specifically unblocked shot attempts and all shot attempts, are predictive at a team and individual player level in regards to future goals scored. This is a great metric to analyze a team overall, but what do these statistics really tell us about the individual player? In reality, not much. Yes, they tell us that certain players appear to “drive possession” for their teams, but they do not show us why or how.
Based on the limited statistics currently available outside of tracking individual games I did some work in trying to identify a subset of individual based statistics to attempt to give a reasonably reliable metric to tell us which players created the most shot attempts for their teams, thus leading to goals for. Taking into account a players role is essential as well as usage does have an affect on all their individual statistics whether a player is asked to fulfill an offensive or defensive role.
In doing a correlation study of various statistics and how they relate to goals I found a combination of stats that are valuable indicators of overall shot attempts while on the ice at the team level. I used data from WAR-on-Ice.com and will include their statistic abbreviations here. They are giveaways (GV), takeaways (TK), penalties drawn (PN-) and personal unblocked shot shooting percentage (PFenSh%).
Each of these statistics requires a player to have possession of the puck. They all speak to the skill of the player, the more skilled the player generally that means more time with the puck on their stick.
As opposed to tracking the positive result of possession being a shot attempt, we are attempting to track the events that cause shot attempts. Giveaways are in general a less desired statistic, however it does show which players have the puck on their stick most often. Takeaways show which players can gain possession for their team and penalties drawn will generally require the player to have possession of the puck as well. The unblocked shot attempt shooting percentage simply adds an element of how skilled the player is at scoring for their team.
I used all data from the 2007-2008 NHL season to present day at five-on-five score adjusted rates for this study. Based on the combination of these statistics there is a 79% correlation to goals for on ice and over a 78% correlation to scoring chances, all shot attempts and unblocked shot attempts for. That is less than the 93% minimum correlation that goals for has with scoring chances, all shot attempts and unblocked shot attempts for. However these statistics can give us better insight into which players are contributing to a team’s possession and goal scoring rates to a greater degree.
So which players were the highest rated since 2007-2008 in regards to what I will call at this point Player Possession Contribution (PPC)? I will break this down using the top five PPC ratings for forwards and defenders separately.
Forwards (Best Season)
1. Pavel Datsyuk, Detroit Red Wings, 2007-2008 (7.0 Sh%, 45 GV, 103 TK, 34 PN-)
