The Forest from the Trees: A post for the stats nerds

He was seriously good in 04. Never quite that good ever again though.

Damn good player. Later in his time with us he seemed more unsure with his decision making - that may have been a function of player movement up ahead or lack of confidence in the options presented to him. Kicked a lot of goals for a guy playing off half back a lot.

McPhee at his best vs Ridley at his best would be a difficult choice.

We got bashed by the hawks in 2004, McPhee copped a fair bit of it. We never responded. We’ve been scared shitless ever since.

Figured I’d post a couple of charts which use Blitz’s favourite stat to tell a slightly different story of our season compared to what the ladder (and some of our memories) have done.

DISCLAIMER: Yes, I am aware that Expected Score (xScore) does not tell us who deserved to win a match of football. Good kicking is good football, etc. What it does quite however well is illustrate how well a team converted its shots at goal, as well as roughly the quality of chances that were created.

Chart 1
My interpretation of this chart is that we rode our luck a fair bit over what some remember as the “part of the season where we were playing good footy”. There are some caveats, such as the Bulldogs kicking some junk time goals which don’t reflect the state of that game, but that also applies to our game vs Melbourne, so swings and roundabouts.

I have labelled the difference between Essendon’s xScore and the opposition’s xScore for clarity:

Chart 2
Here’s another chart showing the difference between Essendon’s actual score and its xScore, compared to the difference between the opposition’s actual score and its xScore. This one gives a better indication, at a glance, of how well each team converted compared to what would be expected:

The Hawthorn game was a really good example of Essendon kicking incredibly well while Hawthorn kicked poorly in the same conditions. Carlton was the complete inverse despite Essendon kicking junktime goals late, which somehow flatters Essendon’s conversion in what was a night of missed chances while the Blues took theirs.

While we were understandably furious with the Adelaide loss a couple of weeks back, the Crows kicked incredibly well for goal. In that regard, we probably caught them at their most clinical.

Hope these are slightly interesting. I may post a few more since it took so long to manually put the data together.

My gut feel has been that, ever since Ridley returned, our backline has been somewhat dysfunctional.

That last chart is quite extraordinary. It suggests that every opponent is outperforming on scoring accuracy since that Richmond game (when Ridley returned). Did he disturb some ancient Egyptian curse or something.

Shut up, Hawk apologist/propagandist.

The response was 7 goals in 14 minutes and winning by 74.

That they “won” the suspensions 15-1 has nothing to do with the ongoing form of the two teams in the following years.

This must mean we’re the fittest team!

I would argue that 0.77 rotations difference between Melbourne’s first and last is far from a “meaningful” difference! I don’t think that this data shows much of note.

The more interesting data for mine would be what teams are doing when the scores are close - in tight games do teams rotate more or less?

The other interesting data would be which players are rotated. Is there a trend to rotate mids more than forwards/defenders? Talls more than smalls? etc. Do teams do this differently?

My uneducated guess is that games with the least rotations are those where there are blowouts, say 30+ points. The stars get taken off for as a risk mitigation etc. Otherwise teams follow the plan of around 17-18 changes a quarter.

My interpretation of those stats was “Brad’s tried nothing, and is all out of ideas”.

Does anyone know how long a midfielder spends on the park before being rotated? Is there an average time spent onfield per mid?
I’m guessing around 11 minutes.

Top player ratings for 2025 round 1 all teams

Player ratings for 2025 round 1 Essendon

Martin gets cheap kicks, his pressure disposal is putrid in the last game cost us 2 goals

He does a lot of hard running to get those cheap kicks and usually his disposal is very good although he has the occasional clanger

Interesting variations between the 3 methods. Perkins rates much worse in Supercoach & Fantasy Points.

My understanding is that fantasy points isn’t a rating system. It simply assigns points to a given stat.

SuperCoach is a bit more advanced and accounts for what type of possessions a player gets and the outcome of that possession.

Ratings system accounts for position played and team outcomes

Martin is allowed to run free, which works well as a loose man, but his pressure disposal is not good

Just to add some extra details:
it’s a measurement of direct impact each player has on a game through their actions that affect either the ball or ball-carrier, expressed as scoreboard impact.

To get this measurement three factors are considered for each action:

  • The location of the ball on the ground before and after the action
  • The situation before and after the action
  • The difference in Next Expected Score (NES) value before and after each action

Actions that increase a player’s team’s chances of scoring next (e.g., taking possession, moving the ball forward) give positive ratings and actions that decrease those chances (e.g., turning it over, missing shots at goal) give negative ratings. The PR each player gets at the end of a game is the sum of these ratings.
