The Penguins Win Meant Redemption For The Numbers Too

2014Kings1 2015Blackhawks1 Corsi is event-, score- and venue-adjusted.Source: Puckon.net, Hockey-Reference.com When the Pittsburgh Penguins won the Stanley Cup on Sunday night, it lifted Sidney Crosby’s standing among the game’s all-time greats and completed the redemption-story arc for once-maligned winger Phil Kessel. But it also provided some measure of atonement for hockey’s advanced statistics, which had been suffering through one of their worst seasons since hitting the scene in the mid- to late 2000s.For instance, “Corsi” — the proportion of total shot attempts (including misses and blocks) that a team amasses in its games — is a stathead favorite because it tracks well with possession time, making it a good long-term predictor of a team’s success. But Corsi also did a relatively poor job of telling us where a team would finish in the standings this season: 2009Penguins13 Stanley Cup winners have great Corsi ranks 2011Bruins6 2016Penguins2 2008Red Wings1 2012Kings6 2007Ducks8 And despite Corsi’s track record in the playoffs, the numbers were dealt a few early blows when the Los Angeles Kings (who ranked No. 1 in regular-season Corsi by some distance), the Anaheim Ducks (No. 5) and the Chicago Blackhawks (No. 9 this year but No. 1 last season) all bowed out in the first round of the Stanley Cup playoffs.But things got a little better for the stats as the postseason grinded along. The Eastern Conference finals pitted the Penguins (No. 2) and the Lightning (No. 3) in an elite Corsi-off, while the sixth-ranked Blues made it to within two wins of the cup final in the West. At No. 11, the Western Conference champion San Jose Sharks weren’t anyone’s idea of a possession powerhouse — they would have been the lowest-ranked champ since the Penguins, of all teams, won in 2009 — but Pittsburgh’s victory ultimately contributed to a stat that still stands out as surprising (and impressive) for a sport that, at times, seems so random: 55 percent of Cup winners since the lockout have finished either first or second in Corsi. 2013Blackhawks1 2006Hurricanes15 SEASONCUP WINNERCORSI RANK 2010Blackhawks1 The fact that Pittsburgh did it in such possession-heavy style — the Penguins outshot the Sharks 353 to 267 in the final — was just an added bit of vindication for the numbers. Hockey’s advanced analytics movement still has a long way to go in its evolution, but even in a down year for the metrics, the cup winner ended up being a team with proven statistical bona fides.
