It’s rubbish and doesn’t deserve attention.
Josh Gibson was winning B&F’s in premiership years but for some reason rarely gets a mention in ‘best of’ arguments.

Isolating individuals in a game with 18 on the field is inherently difficult (flawed?) yet it’s literally what 3/4 of this forum is about (the rest is Nino and DJ king). It’s no different for stats.
Regarding team defence, I think it’s fair to say Lynden Dunn benefitted from playing in a side with manic pressure. But even with that factored in, he’s clearly had a fair season.

One On One is one of the simplest metrics to define in a game - It’s when two players are contesting an aerial ball - Nothing more or nothing less - And the Hurley figures seem about right - And arguments about Hurley being an extra defender have no bearing on this stat.
Absolute rubbish.
Unless you know the exact question, the answer is meaningless and interpretable. No stats of this sort given to the public, without absolute clarity regarding the process, mean anything other than what you want it to mean.
Anyway - once again, one of those subjects that is far too deep to discuss properly here.
One on One is One on One, no matter how you cut it, dice it or spin it.
You’re underestimating the sophistication of CD and their highly trained stats people / observers.
They can devise definitions so cunning they’re beyond the ken of mortal supporters.

Except you don’t start every one on one with P(win) = 0.5
P(Half) +P(win #A) +P(win P2) + P(free for P1) +P(free for P2)=1
P(half) might be ~0.5 where 2 players are evenly matched.
Good article this:
If you did start every contest with the players having to work out the meaning of that formula, there would be a lot of stoppages in play.

But didn’t they all get 99.9 ATARs. That’s what the media always tells us!
most stats nerds needed to do better with english, so anyone could care what they had to say.
Or the rest of society could get some basic understanding of numeracy.

Heather mills has gone out for a hop. I am sure she will respond when she gets back.
This is not the justifiably criticised CD player Ratings, this is arrived at by noting who is at each centre bounce, then noting if score results from that combination ( based on some rules we don’t know )
How could our average lot of ruckmen and mids be better than the elite combos of Melbourne and Collingwood at centre bounces?
How is it that the best midfield in the competition, Geelongs A list set of mids with 3 brownlow medals between them is not in the top 10 ?
It cannot possibly be true.
Quite clearly there is more to a midfields rating than that, because 5.6% is not good. At all.
Lets hope they worked on this in the off season.

Again - this means little. It does not take into account any detail. Like for example - the opposing group of mids. The state of the game at any particular time. The weather. The ground. Comparisons to other combinations of mids from the same team. The momentum of the game at those points. Whether in a winning or losing position at the time. The time period logged. Game plan. Efficiency of ruckman. First possession efficiency. Who that was. Who it was opposed to. Opposition ruckman. Negators vs pure offensive.
I could go on indefinitely. The point is - statistics is data. Raw data is important and useful. Drawing clean, clear, itemised and listed conclusions from it approaches impossibility, unless you either have a very simple system, or compromise the result to appease the consuming audience. This is akin to that ridiculous screen put up in THE LAB.
The statistics for kick-ins is a far, far simpler stat. It narrows things down immensely from the clearance one. But the pure form of it would be - 1 player kicking the ball to another player, who tries to mark it. Basically - kick-to-kick. The more you add to that, the more it becomes complex until it gets to the stage of what I described above.
