I hear you Polly.
Stats in general are, to various degrees, flawed regardless of how good the stat itself might be (in the case of some of the non-public Champion data stuff). Let alone publicly available stuff that i use as the basis here which is, in the main, flawed. Some of it a little more robust than others but we do our best to paint some sort of picture with the limited stuff we have available to work with.
Now the one thing that stats don't do (at least the publicly available ones and probably even most of Champion data's with maybe some exceptions) is measure things like you have highlighted. Crashing packs, going back into an on coming marking contest. Going back with the flight or laterally to spoil a boil with courage as we saw with Vanders yesterday. All they are there to do is try and capture a very basic overview of who produced what results / output on the day in a very rough guide sense that may (or may not) be an indicator of who performed sub par, ordinary/average, above average, good to very good or excellent to off the charts. They generally don't cover the points you highlighted and they certainly don't cover things like a lock down player playing his role in keeping a top opponent's output well down below his usual. A defender keeping a top KF very quiet vs his usual. A KF having a somewhat quiet day up forward but still doing the little things at the contest that bring others into the game, score assists, spoils from behind, hit outs to advantage when taking forward ruck duties etc.
Stats also don't measure the quality of an opponent or the opposition.
These are all analogue / qualitative factors which sometimes get overlooked with pure stats alone.
That's why i always say, don't judge any player on stats alone and certainly don't look at these weighted scores in isolation wherever possible.. Watch the entire game first and determine for yourself how that player went as stats alone can never capture the entire story of what went on on the field. A very rough guide that sometimes works and sometimes a fair way off, sometimes partially correct.
With regard to Weid's output in this particular match and what made up his lowish output / score of 1.375 and a ranking of 19th on the day? Let's look at what went into that score. 5 effectives running at 62.5% efficiency. About 10% below the AFL average although i don't know what that is for KFs. Probably somewhat less than 73% given the pressure they're under. One contested mark, three marks inside 50, two 1%ers, two inside 50s, one tackle (inside 50), three score involvements, two goals and two turnovers.
Now let's look at the previous week where he finished with a score of 2.675 and equal 9th alongside T-Mac against the Roos in Rnd 11. He had 10 effectives running at 76.9%, roughly 4% above the AFL average DE %. three contested marks, five marks inside 50, two 1%ers, eight score involvements, two goals and two turnovers.
As you can see, more than double his effective disposals against the Pies, nearly twice as many marks inside 50 and two extra contested marks. Add to that nearly three times as many score involvements. Same goals, same turnovers. So in many areas more than double the output with the same score and turnovers, producing a statistical weighted score just under twice that of his match against the Pies. As you can see it's merely the statistical results / output produced on the day that make up this score.
Did he play an ordinary game against the Pies however? In my view no. He contributed and still produced the same number of goals, brought the ball to ground on occasions as you have highlighted. He played his role. Was his match against North nearly twice as good in comparison? Really hard to call. Honestly, i forget much of what happens in most matches fairly quickly and would need to watch it again and then watch the Pies match again to be sure. And who has time to do this? If i was getting paid for it...maybe!
He contributed nicely yesterday and we won by a very solid margin. As did Vanders albeit he didn't rack up many possessions and turned it over quite a bit. He also played his role in various ways throughout the day, played a hard at the pill game and lead the way with a number of courageous acts. As we know, those courageous acts (aside from the actual spoil against opponent itself as a 1%er) aren't captured in this data.
It is what it is as they say and we spifflicated the Pies. All is well!
