SJ@LA Game 1: Per Possession

leave a comment »

I tracked games 1 and 2 of the LA Kings-San Jose Sharks playoff series on a per possession basis.  I am essentially documenting how each even strength possession ended for each team at 5v5.  Possessions are defined as one team having possession of the puck anywhere on the ice, followed by their opponent gaining possession.  Below is a Game 1 breakdown of how each even strength possession ended for each team in:

To the right of each count is the % of possessions that particular event ended for that team.  As you can see, 28% of Los Angeles’ possessions ended in Offensive Zone Turnovers, as compared to 25% for San Jose.   San Jose had 13 clearances through periods 1 and 2, compared to 13 in the 3rd period alone.  This is a result of San Jose dropping into defensive shell to protect their 4-3 lead.

Below I breakdown Offensive and Defensive Zone Turnover%, where each team’s turnover frequency is evaluated based upon how they committed turnovers while in possession of the puck in the offensive and defensive zones:

You’ll notice that the Defense zone possession counts are higher than the offensive zone possession counts.  This is due to the fact that failed dump ins and clearances into the opponents’ offensive zone are factored in to the “defensive zone possession” count.  Both San Jose and Los Angeles were almost even in turnover efficiency in each zone.

Overall possessions at 5v5 were:
Los Angeles: 151
San Jose: 155

Factoring in even strength(5v5) shots on goal, you can see how productive each team was when they obtained possession of the puck:

Los Angeles had 14 SOG at 5v5, therefore (14/151)= 9.3 SOG Per 100 Possessions
San Jose had 18 SOG at 5v5, therefore (18/155)= 11.6 SOG Per 100 Possessions

Now looking at just Offensive Zone Possession Efficiency:

Los Angeles had 14 SOG on 64 Offensive Zone Possessions,
therefore(14/64)= 21.9 SOG Per 100 Offensive Zone Possessions.

San Jose had 18 SOG on 58 Offensive Zone Possessions,
therefore(18/58)= 31 SOG Per 100 Offensive Zone Possessions.

San Jose appears to have been the more efficient team based on Offensive Zone Efficiency, achieving 8.1 more SOG per 100 Offensive Zone Possessions than Los Angeles in game 1.
