Moneyball theory reveals which AFL teams will rise and fall in 2020February 25, 2020

FOX SPORTSTEAMS THAT OVERPERFORMED IN 2019 (Should fall in 2020)
RichmondPoints for/against in 2019: 1892/1664 (percentage of 113.7)
Actual wins: 16
Pythagorean wins: 13.6
This is one of those cases where the stat doesn’t quite pass the eye test. But let’s look at what Pythagoras is saying here.
The Tigers were clearly the best team in the AFL by the end of September, and deservedly demolished GWS in the Grand Final. From the bye, where Richmond sat 7-6 with a percentage of 92, Damien Hardwick’s side won 12 consecutive matches.
In the first half of the year the Tigers were ravaged by injury, so in a sense those are two different teams we’re analysing; the pre-bye Tigers who clawed their way to a winning record, and the post-bye Tigers who roared towards another flag. The pre-bye performance drags down the percentage of the post-bye team.
But let’s look at it the other way. Is Richmond going to go undefeated in 2020? Almost certainly not. The Tigers were famously the beneficiaries of a kind run home that saw them play their last seven games of the home and away season at the MCG. Who’s to say they wouldn’t have lost to West Coast in Round 22 if that game was played in Perth, rather than Melbourne (where they won by six points)?
To put it more simply: the Tigers probably aren’t as good as a 12-0 run to end the season says they were.
We’re putting an asterisk on this. When putting together our predicted ladder, we’re not going to tip Richmond to fall out of the top four, but let’s maybe use this and say they won’t completely run away with the competition.
