Corsi (CF%) tracks the percentage of a shot attempts teams manage in games. This handy statistic roughly correlates to puck possession.
Corsi close limits itself to situations within one goal in the first two periods and tie games in the third. Teams tend to sit back with bigger leads, which skews the numbers. For this reason, corsi close paints a truer picture than raw corsi totals.
Over the last decade, seven of the 10 Cup winners ranked top three in the league in even strength corsi close. Furthermore, 13 of the 20 Cup finalists ranked in the top six.
