Understanding stats

Featured Replies

Posted

I don't get involved in Dreamteam, etc, but I still like to review stats of games. But I have a couple of queries I'd like some help with.

Query Number 1:

According to the AFL website, Nicho had 5 contested possessions and 10 uncontested possessions against PA. My maths tells me he had 15 possessions (unless there is another type). But he had 10 disposals. I can accept that discrepancy if it means there were 5 instances where he got caught with the ball and didn't dispose of it properly, or he got possession at the end of a quarter and the siren went. If that logic is correct, what I can't understand is how the same website says Frawley had 4 contested possessions and 10 uncontested possessions yet 15 disposals. How does that work? How can he have more disposals than possessions?

Query Number 2:

What is G%, which the wesbite helpfully tells me is "Goal Accuracy Percentage"? Every player has a number yet only 9 kicked goals last night. Is it meant to be each player's longterm accuracy? If so, has James Strauss ever kicked a goal...and if he hasn't how can he have an accuracy rating of, apparently, 84%?

Any help gratefully received.

Second would be time on ground %.

Not sure on the first.

I suspect you're right about the second. Nice of the AFL website to be so misleading. Who would have though "Goal Accuracy Percentage" actually meant "Time on Ground Percentage".

 

I cannot fully explain point one, but have read the definitions for 'contested' and 'uncontested' possessions used by the stats dept are something like those that follows:

-A contested possession is one where the ball is in dispute, which will therefore include loose ball gets (i.e. bombed into space, you run over and pick it up) and hard ball gets (two players dive for the ball, one gets it).

-An uncontested possession is one in which you receive the ball from a team mate (i.e handball receive, or mark).

I am not sure of how a contested mark is viewed (it would be strange if it wasnt a 'contested' possession), although strictly speaking it could fall into both categories. I am also not sure if 'they' have decided that loose ball gets in space with no real contest is actually an uncontested possession (this would introduce a subjective grey area.

Obviously there are lots of possessions that do not result in correct disposal, in fact there are way too many than there should be (dropping or releasing the ball appears acceptable these days).

With regards to the Frawley situation, my only thoughts are kicks off the ground (where disposal is never taken), unless the definition of contested and uncontested possessions are such that some possessions do not actually fit these criteria?

Re point 1: quite simply, taking possession of the ball (i.e. a possession) does not always result in a disposal. The two terms have different meanings.

If you are tackled and the ball spills free?

I don't disagree. But it hasn't answered the converse. How can Frawley have had more disposals than possessions? Another poster has suggested a kick off the ground. Perhaps that's the answer.

I'd say that's almost certainly the answer - or a kick out of mid air a la Alan Didak or Marco Breciano.

Is this a coincidence? Or does someone at the AFL monitor Demonland Forums?

Not long after querying in this thread the 'G%' which according to the AFL website was measuring 'Goal Accuracy %', but wasn't, the AFL stats have now been fixed so it has the correct reference to time on ground.

[You can't see me, but assume I've got a self-satisfied smirk happening. And, yes, I'm easily satisfied.]

  • PREVIEW: Essendon

    As the focus of the AFL moves exclusively to South Australia for Gather Round, the question is raised as to what are we going to get from the  Melbourne Football Club this weekend? Will it be a repeat of the slop fest of the last three weeks that have seen the team score a measly 174 points and concede 310 or will a return to the City of Churches and the scene where they performed at their best in 2024 act as a wakeup call and bring them out of their early season reverie?  Or will the sleepy Dees treat their fans to a reenactment of their lazy effort from the first Gather Round of two years ago when they allowed the Bombers to trample all over them on a soggy and wet Adelaide Oval? The two examples from above tell us how fickle form can be in football. Last year, a committed group of players turned up in Adelaide with a businesslike mindset. They had a plan, went in confidently and hard for the football and kicked winning scores against both home teams in a difficult environment for visitors. And they repeated that sort of effort later in the season when they played Essendon at the MCG.

  • PREGAME: Essendon

    Facing the very real and daunting prospect of starting the season with five straight losses, the Demons head to South Australia for the annual Gather Round, where they’ll take on the Bombers in search of their first win of the year. Who comes in, and who comes out?

  • NON-MFC: Round 05

    Gather Round is here, kicking off with a Thursday night blockbuster as Adelaide faces Geelong. The Crows will be out for redemption after a controversial loss last week. Saturday starts with the Magpies taking on the Swans. Collingwood will be eager to cement their spot in the top eight, while Sydney is hot on their heels. In the Barossa Valley, two rising sides go head-to-head in a fascinating battle to prove they're the real deal. Later, Carlton and West Coast face off at Adelaide Oval, both desperate to notch their first win of the season. The action then shifts to Norwood, where the undefeated Lions will aim to keep their streak alive against the Bulldogs. Sunday’s games begin in the Barossa with Richmond up against Fremantle. In Norwood, the Saints will be looking to take a scalp when they come up against the Giants. The round concludes with a fiery rematch of last year's semi-final, as the Hawks seek revenge for their narrow loss to Port Adelaide. Who are you tipping this week and what are the best results for the Demons besides us winning?

  • CASEY: Geelong

    There was a time in the second quarter of the game at the Cattery on Friday afternoon when the Casey Demons threatened to take the game apart against the Cats. The Demons had been well on top early but were struggling to convert their ascendancy over the ground until Tom Fullarton’s burst of three goals in the space of eight minutes on the way to a five goal haul and his best game for the club since arriving from Brisbane at the end of 2023. He was leading, marking and otherwise giving his opponents a merry dance as Casey grabbed a three goal lead in the blink of an eye. Fullarton has now kicked ten goals in Casey’s three matches and, with Melbourne’s forward conversion woes, he is definitely in with a chance to get his first game with the club in next week’s Gather Round in Adelaide. Despite the tall forward’s efforts - he finished with 19 disposals and eight marks and had four hit outs as back up to Will Verrall in the second half - it wasn’t enough as Geelong reigned in the lead through persistent attacks and eventually clawed their way to the lead early in the last and held it till they achieved the end aim of victory.

  • REPORT: Geelong

    I was disappointed to hear Goody say at his post match presser after the team’s 39 point defeat against Geelong that "we're getting high quality entry, just poor execution" because Melbourne’s problems extend far beyond that after its 0 - 4 start to the 2025 football season. There are clearly problems with poor execution, some of which were evident well before the current season and were in play when the Demons met the Cats in early May last year and beat them in a near top-of-the-table clash that saw both sides sitting comfortably in the top four after round eight. Since that game, the Demons’ performances have been positively Third World with only five wins in 19 games with a no longer majestic midfield and a dysfunctional forward line that has become too easy for opposing coaches to counter. This is an area of their game that is currently being played out as if they were all completely panic-stricken.

  • NON-MFC: Round 04

    Round 4 kicks off with a blockbuster on Thursday night as traditional rivals Collingwood and Carlton clash at the MCG, with the Magpies looking to assert themselves as early-season contenders and the Blues seeking their first win of the season. Saturday opens with Gold Coast hosting Adelaide, a key test for the Suns as they aim to back up their big win last week, while the Crows will be looking to keep their perfect record intact. Reigning wooden spooners Richmond have the daunting task of facing reigning premiers Brisbane at the ‘G and the Lions will be eager to reaffirm their premiership credentials after a patchy start. Saturday night sees North Melbourne take on Sydney at Marvel Stadium, with the Swans looking to build on their first win of the season last week against a rebuilding Roos outfit. Sunday’s action begins with GWS hosting West Coast at ENGIE Stadium, a game that could get ugly very early for the visitors. Port Adelaide vs St Kilda at Adelaide Oval looms as a interesting clash, with both clubs form being very hard to read. The round wraps up with Fremantle taking on the Western Bulldogs at Optus Stadium in what could be a fierce contest between two sides with top-eight ambitions. Who are you tipping this week and what are the best results for the Demons besides us winning?
