Toronto at Pittsburgh 2-17-18
Individual Possession Analysis
Pittsburgh 5, Toronto 3

The below charts are the results of my individual possession tracking.  Documenting what each player does per each individual possession they have at 5v5.  Corsi%’s were retrieved from corsica.hockey.  The below chart shows each player’s turnovers per possession, and which zone they occurred in.

The “turnovers per possession” column represents the percentage of the time a player committed a turnover per their individual possession totals at 5v5.  Now what immediately stands out is that Sheary, Guentzel, Crosby, Kessel, and Aston-Reese all had high turnover rates above the team average for the game of 28%.  On average, about half of these turnovers occurred in the offensive zone, and about 25% of total turnovers resulted from a clearance out of the zone or a dump in.  These five players altogether combined for 1 defensive zone turnover, so they were not putting their team in a harmful spot.

Ian Cole posting the highest corsi% at 76.5%, while also posting the 2nd lowest turnover rate per individual possession at 13%.  Cole’s passing accuracy% for the game was 83%, which is above the team average of 77%.

The chart below shows each players’ shot attempt efficiency per individual possession at 5v5.  (SOG+Missed+Att Blocked)/Possessions = Efficiency%.  Average Shot Attempts per possession were 12%, meaning for every 8 individual possessions a player attempted 1 shot.  The shot attempt assist per possession average was 8%, meaning per every 12 individual possessions, a player would pass to a teammate who then attempted a shot.

Kessel is a very efficient shooter, basically attempting a shot ~1 out of every 4 individual possessions.  Malkin and Crosby led the way in shot attempt assists at 26% and 21% respectfully.   So basically, for every 4 individual possessions on average, Malkin and Crosby passed the puck to a teammate who attempted a shot.

Above, you can also see offensive and defensive rebound percentages at 5v5.  A rebound is classified as when the puck is retreived by a player following any shot attempt (SOG, missed, attempt blocked) that remains in play.  So pucks that are deflected out of play or frozen by the goalie are deducted from the available rebound totals for each player.

Team average offensive rebound% was 8%, and defensive rebound% 6%.  Carter Rowney leads the way, posting a 25% rebound%. Obviously playing limited minutes and only totaling 7 individual possessions at 5v5, Rowney obtained 1 offensive rebound of the 4 available.  Ian Cole posted the highest defensive rebound% of 33%.  Maatta and Hunwick both struggled to rebound defensively, and their corsi%’s of 47.6% and 42.1% highlight those issues.

Team average passing accuracy by zone:  Offensive: 70%, Neutral 74%, Defensive 91%  Blank cells indicate that the player did not attempt any passes to that zone.

Below is a breakdown of each players’ steals, and the zone in which they occurred.  Crosby and Reese apply a tremendous amount of pressure in the offensive zone, constantly pressuring Toronto following a rebound they did not obtain, or a turnover committed in the offensive zone.  Hunwick, Maatta, and Letang did well to cover the points along the boards, in order to prevent easy clearance attempts by Toronto.
