Frozen Tools Forensics: Evaluating IPP

Every so often we turn our attentions to some of the stat categories on the site, include a little primer on what they are and then see how we can use them to give some context to what is happening with certain players. We featured Evgeni Malkin last season in our review of IPP. Today it’s Jordan Kyrou.

IPP or Individual Point Percentage is a measure of how often a player receives points on a goal that is scored when they are on the ice. It can more colloquially be referred to as point participation as well. So if five goals are scored when a player is on the ice and they get the goal, or an assist on four of them their IPP would be 80 percent. The stat alone is interesting, but it really gets to be helpful when we have something to compare it to. For instance, we know that forwards tend to have a higher IPP than defensemen. This makes sense as forwards tend to be in position to score more often. We also know that elite forwards tend to have a higher IPP than bottom six forwards, with your elite players reaching potentially 75 to 85 percent. What is most helpful though is comparing a player's current sample size to a recent, larger sample size. For example, Alex Ovechkin's current IPP is 76.9 percent. Ovechkin is an elite forward and that is certainly within the range of other elite forwards so we might not think anything of it. However, there is only one season where Ovechkin participated on more than 70 percent of the goals scored when he was on the ice, and over his last four seasons he has been closer to 63 percent. In this case the inflated IPP means that either something has changed in his game/deployment, or he is getting in on more points that we should expect, and his IPP (and therefore his point pace) will likely drop somewhat.

On Frozen Tools there are a number of places where you can find IPP. For individual players it is listed under the Advanced Tab, and it is included in a number of reports. For our purposes today we are going to focus on the IPP report, because well, we are talking about IPP.

For starters let's take a look at our top participators to date (all data in this article pulled Jan 6, prior to any games played that day).

Since IPP is a percent, it covers all players and point totals, so those who were on the ice for one goal and got a point will have an IPP of 100. Given that I put in a points cutoff of 15 so we are looking only at players who have a reasonable number of opportunities.

Leading our list here is Jack Hughes. He also has the smallest sample, both in terms of points, and games played, so is likely the most variable. This list also gives us an opportunity to highlight a couple of other features of IPP. IPP really helps to highlight who the play is
