**Corsi For** Percentage - Total shots (on goal + misses + blocked). In its simplest terms this stat measures the percent of the total shots taken while a player was on the ice that were on the opponent's net vs their own net. ([DT](x-devonthink-item://BC851E29-7A12-4335-9AD7-E41E0FA9EAC0)) **CF%Rel** (Corsi-For% Relative to competition): Corsi is really just a plus-minus stat – but instead of it being strictly for goals, it is for shot attempts (shots on goal, shots that miss, shots that are blocked). Corsi-For% is the difference between that player’s CF% and the team’s CF% when that player is on the bench. CF%Rel is the above number, but it adjusts for the competition on the ice (i.e. takes into account if the player is on the ice against top players, while the rest of the team is out there against lesser lines). (Dobber) **Expected Goals Percentage -** the expected goals metric takes a stat like the Corsi For Percent and adjusts each shot based on its 'danger' – a shot taken from a more dangerous location is worth more expected goals. ([DT](x-devonthink-item://BC851E29-7A12-4335-9AD7-E41E0FA9EAC0)) **Fenwick –** Corsi minus blocked shots. **Fenwick** exists so we can add shot quality into the mix a bit. If you are getting your shot blocked, you’re likely taking a low quality shot. So **Fenwick,** imo, is a bit more important. ([DT](x-devonthink-item://7E54D430-8DCD-4515-8600-D408C75AD1E4)) **Fenwick save percentage** - the difference between expected saves and actual saves ([evolving hockey](https://evolving-hockey.com/glossary/home/)) **5on5 S%**: This is the shooting percentage of a player and his teammates when that player is on the ice. More important than PDO in fantasy hockey, though it makes up only part of the formula. Generally speaking, a player who is on the ice when his teammates (and himself) are shooting 5.5% is going to get more points next season just from the puck going in at the proper rate (i.e. ‘market correction’). League-wide, the average shot percentage is about 9%. Actually, it was 8.89% last season and 9.13% the season prior. The average player, over enough games, will see his 5on5 S% approach that number. (Dobber) **IPP** (Individual Points Percentage): This is the percentage of the goals scored by a player’s team while he was on the ice, on which he picked up a point. This is mainly useful when looking at it year over year. A decline in this number is an indicator of an erosion in talent, often due to age or injury. ([DT](x-devonthink-item://930A4F05-28C8-40DF-ACC8-936D344B4485)) ([Dobber](https://dobberhockey.com/2022/01/07/frozen-tools-forensics-evaluating-ipp/)) **%PP**: The percentage of a team’s available power-play time that a player is on the ice. If it is over 60%, you can safely assume that player is on the first power-play unit. Useful for comparing a player to a teammate who plays the same position – who is favored more to get the PP ice time? (Dobber) **PDO** (aka ‘SPSV%’) **–** on ice Shooting % + on ice Save %. **PDO** is going to determine how lucky or unlucky you have been. Most forwards average around 10% shooting (i.e. 10 goals on 100 shots) and goalies generally save 90% of shots, for a total of 100%. Essentially, the lower your PDO, the unluckier you’ve been and vice versa. So if a player has a PDO of 120% over a certain period of games, you can assume they will see some regression. ([DT](x-devonthink-item://7E54D430-8DCD-4515-8600-D408C75AD1E4))([DT2](x-devonthink-item://65EEADCC-D5BD-41BC-99B6-F8ACE38161EF)) I find that I now use this one less than in years past, focusing instead on the 5on5 S% component. PDO is a good statistic to quickly draw your attention to any player with an abundance of luck (good or bad). It takes the 5on5 S% + 5on5 SV% and the distance it deviates from 1000 tells you if he was the victim (or beneficiary) of some lucky bounces. But since fantasy hockey is mostly about offense, focusing on 5on5 S% is more prudent. (Dobber) Pts/60 (Points per 60 minutes of ice time): This is pretty self-explanatory. Since ice time is not equal across all players, what happens when we make it equal? A great way to see how up-and-coming players are doing with the ice time that they are given. (Dobber) **QofC** (Quality of Competition - aka CorsiRel QofC): This is a way of measuring how strong the competition is that a player sees throughout the season. A player seeing the top line every game would obviously see a QualComp number on the high end of the scale (say +1.20). A player seeing the fourth line every game would see something closer to -1.20. It's measured by taking the average of the CorsiRel of each player on the opposition that’s on the ice. Seeing a high number here tells you that he's in good with the coach and can expect more responsibility next year (if it's a young player), or that he’s a superstar (if it's a veteran). (Dobber) **TOI** (Time on the Ice): I like to look at a player's ice time and power-play time to see if he is being used the way he should. It’s really only an issue with young players, or one-dimensional players. I also like to see if the ice time in general was moving in an upward direction as the season went on. Seeing a rookie getting time on the penalty kill is also a good reflection of the coach's trust. Our player profiles also have ice broken down quarterly on the main page – a great way to see at a glance if he’s getting more trust or less trust from the coach. (Dobber) **ZS%** (Offensive Zone Start Percentage): What percentage of a player's shifts begin in the offensive zone? If the number is 65%...then he's either being pampered by the coach, or he's being leaned on by the coach to score goals. Often both. If that number is 35%, then he's obviously a checker, and even if he's putting some points on the board, it's probably safe to assume that his production is not going to improve in the season ahead.
