Who will win the 2019 NRL Premiership?

At this time of year, is there anything else you want to know more than the answer to this question?

For our crystal ball, we turn to Monte Carlo simulations. These simulations work on the principle that if we know the inputs to a complex system and how they relate to each other, then we can test the outcomes of that system using random numbers to simulate different situations.

At its most basic, just imagine if you simulated the outcome of football matches by rolling dice. Numbers one and two might represent a win for the Gold Coast and numbers three through six might be a win for Wests. If you repeat that a couple of thousand times, not only will you be extremely bored but the Gold Coast will “win” about 33% of the time and Wests 66%.

Now take the same approach for the nine finals games, with the winner advancing per the NRL’s system, but instead of using dice, you generate a random number between zero and one and calculate the win probability using Archimedes (form) Elo ratings. Then repeat it 5,000 times over. The number of times that the Storm or Roosters or Broncos or Eels “win” the premiership across your simulations should give you some insight into the probability of that happening in real life. I call this the Finals Stocky and I present its findings.

A Complete History of the NRL

Two weeks ago, you may have (but almost certainly did not) read my Complete History of the NRL: Nerd Edition.

Actually, there wasn’t much to read in the way of words and for those who aren’t so inclined to dealing with Elo ratings, Pythagorean expectation and counting premierships, possibly because you’re an Eels fan and don’t remember what victory feels like, I’ve prepared a simpler edition of the Complete History of the NRL.

The history is presented in a series of colourful graphs. The graphs track each team’s win per season and are helpfully annotated to remind you of great moments in NRL history.

And if you’re familiar with the work of Jon Bois, you’ll recognise this as eerily similar to his History of Every NFL Team video, which I have shamelessly ripped off for content.
