Pittsburgh at Philadelphia 3-7-18
Individual Possession Analysis
Pittsburgh 5, Philadelphia 2

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.  The average corsi% was 50% and the average turnover% was 26%.

Hornqvist seem to almost have a perfect game in regards to turnovers.  Posting a 9% turnover rate at 5v5, which was the lowest on the team.  Bryan Rust was injured early in the 1st period, so his individual possession sample size of 4 really isn’t going to tell us much about his 66.7% corsi% to that point.  This chart seems to be more straightforward in presenting a much clearer picture in that, as corsi% gets lower, the turnover rates increase for each player.

The Kessel-Brassard-Simon line posted a 38.3% corsi% on average, well below the team average of 50%.  This line’s average turnover rate was 44%, as the team average was only 26%.  A lot of this stems from the line’s inability to put passes together in the offensive zone.  The other 3 lines were able to complete a pass in the offensive zone on ~25% of their individual possessions, where the Kessel-Brassard-Simon line was at 17%.

The defensive zone turnovers per possession average was 4%, Brassard and Maatta posted the highest rates, at 9% each.  The issue here is that the bottom 2 lines are just dumping the puck in at a high rate.  On average, a dump in that resulted in a turnover occurred on 6.5% of individual possessions at 5v5.  You can see that Kuhnhackl (18%), Sheahan (19%), Ruhwedel (20%), Simon (13%), and Brassard (9%) all posted well below average corsi%’s, which stem from a lack of offensive zone possession and suboptimal attempts to enter the zone.

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 10.3%, meaning for every ~10 individual possessions a player attempted 1 shot.  The shot attempt assist per possession average was 7.8%, meaning per every ~13 individual possessions, a player would complete 1 pass to a teammate who then attempted a shot.

The team average offensive rebound% was 10.6%, and the average defensive rebound% was 11%.  Hornqvist was very efficient at getting shot attempts at 5v5, posting a 26% shot attempts per possession rate, averaging a shot attempt on 1 in 4 individual possessions.  Jake Guentzel was about the team average in both shot attempts per possession and shot attempt assist per possession, as well as team average in rebound rates.  Conor Sheary posted the highest offensive rebound rate of 30%.  Both of Sheary’s goals at 5v5 were the result of a rebound he obtained.

The average offensive rebound% for forwards was 14.7%, and average defensive rebound% was 11.8%.  For defensemen, the average offensive rebound% was 4.4% and the average defensive rebound% was 9.7%.

The chart below shows passes completed by zone per individual possession.  For example, Malkin had 41% of his 34 individual possessions result in a completed pass in the offensive zone(14/34 = 41%).  This chart offers a good estimate as to which zone each player was spending time in during 5v5 play.

The average offensive zone passing accuracy% was 74% as a team, but Kessel was at 67% (4 completed/6 attempted), and Brassard was at 50% (3 completed/6 attempted).  Simon was at 100%, but only on 1 pass attempt.

Jake Guentzel’s passing accuracy by zone: Offensive 89%, Neutral 75%, and Defensive 100%.  Team averages: Offensive 74.3%, Neutral 72.6%, Defensive 86.7%.

The below chart shows a steals analysis and the zone in which the steal occurred.  Hornqvist was able to get 2 steals in the offensive zone, as well as Hagelin.  Dumoulin did quite well in the neutral zone, leading the team with 5 neutral zone steals.  The Kessel-Brassard-Simon line did not get one steal in the offensive zone.  Each other the other 3 lines averaged 2.67 steals in the offensive zone.  Steals can help to offset offensive zone turnovers, in order to maintain zone pressure.
