The overrated value of a faceoff


Every so often, an analyst will talk about how a certain player deserved a “three star” nominee because he won two or three big faceoffs. Even more so often a coach will send out two centremen in a high-leverage situation to win a key, late draw. The question is whether this tactic has a tangible value.

Let’s use the Corsi number here. The Corsi number is, of course, an advanced +/- statistic that counts every goal, saved shot, missed shot and blocked shot while a player was on the ice and is a reliable indicator of which team had possession of the puck when a player was on the ice. Since a won faceoff essentially gives one team possession over the other, logically, faceoff percentage would correlate well to a player’s Corsi number.

In the beautiful, scenic spreadsheets offered at Behind The Net there exists data on 1799 players who have played 60-or-more games over the course of a season. I looked at a few, key bits of data from those players to determine faceoff value.

Microsoft Excel kept crashing on me, so I couldn’t label the chart. However, the Y-axis indicates a player’s Corsi number while the X-axis indicates the team’s faceoff percentage while he was on the ice. I’ve added a trendline, as well:

With an r-squared value of .015, there is little correlative value between winning a faceoff and actually turning the possession into anything tangible.

I ran a similar correlation between where a player started his shift [ Offensive zone starts / Total Offensive and Defensive Starts ] and his Corsi number. Let’s see this result:

The r-squared value is .160. It doesn’t mean that there’s a determination in where you started your shift as to having tangible possession, but it does show us that the location of the puck is more important than who actually has the puck. This is where the dump-and-chase gets away with being a still useful, method of zone-entry. A team concedes possession for puck location and works to get it back in a similar spot.

Oilers blogger Tyler Dellow has looked at the value of a faceoff on the penalty kill recently and I have to add that I’ve come up with a similar conclusion at even strength. There’s a 60-40 split between the top and the bottom regular faceoff men in the league. At 10 draws a game (roughly) that equals two touches of the puck on your defenseman’s stick before anything can happen on the play.

I will add, however, that there are some faceoff specialists who double as strong defensive players: Manny Malhotra, Jarrod Smithson, Steve Ott, Paul Gaustad and [I guess] Selke winner Ryan Kesler had strong seasons on both draws and preventing shots. Players like Zenon Konopka and Jarrett Stoll had less generous defensive numbers, and Jonathan Toews, who came second in Selke voting purely by virtue of his faceoff skill was 169th in shot prevention among the 314 forwards who had played more than 600 minutes this past season.

    As important as faceoffs are and having great centers, I think we may have a more pressing problem on the left wing in 2012/2013. Where is MPS gonna play with Smyth, Hall and Parise ahead of him?

    This just seems like a shot at justifying Connolly’s losing face-off % over Bozak’s Winning face-off %. There are a lot more face-offs than goals. There is where you’re low numbers come from. This should be broken down more into face-off locations and even strength vs. PP vs. PK on a team to team player to player basis. A lot of work to prove anything can happen. Strategies and ability of the opposition to read plays is another tangible. The fact of the matter is you don’t win without possession and the face-off is where it all starts.

    hockey is chaotic.

    thats basically the point of all these lame stats. its chaotic. its not baseball and its not rigid football. small, micro-events always happen that can keep trends from surfacing.

    are faceoffs important? depends.
    is shooting important? depends.

    can you still play sick defense and have the puck go off your skate or body into your own net? sure.

    did Vancouver have the best numbers of the regular season? yes. did determinism dictate they win the Cup? nope.

    numeric determinism in hockey makes hockey boring. chaos and chance is why we watch it. keep winning faceoffs the best you can.

    It isn’t much of a logical stretch to conclude that faceoff losses are more significant to bad teams (teams that can’t regain possession). When the Oilers lost a draw it was balls-deep panic time.

    Meanwhile, I recall a number of instances where the Oil won the faceoff and still couldn’t get the puck out of their own zone or get a shot on goal. Why? Because the other team just took the puck away from them anyway.

    Bad overall hockey players are for more significant to team success than bad faceoff artists.

    i’m sure it has already been said, but some stats must be taken into context. An offensive zone faceoff in the first 5 minutes when the game is 0-0 does not matter as much as an offensive zone start with 30 seconds left when the offensive team is on the powerplay and down 5-4.
