MatterOfStats 2015 : Team Dashboard for Round 1

/

Below is the first Team Dashboard for 2015 and, in keeping with the custom of Round 1 blog posts this season, I'll spend a little time explaining what's in the Dashboard.

The top section is fairly self-explanatory and routine, and sets out details of each team's competition points, overall offensive and defensive statistics, and Win/Loss record. For now, teams are sorted in the customary manner but, once bye season has commenced, I sort teams on the basis of competition points earned as a proportion of possible points earned, which can sometimes lead to orderings that differ from the official ladders.

The middle section records information about various offensive and defensive metrics that I've found to be associated with teams' winning and losing records. This includes information about Scoring Shot production and concession, and the conversion of these Scoring Shots. This week, for example, we see that Adelaide has generated 35 Scoring Shots per game and conceded 18. Also, it's converted 60% of those Scoring Shot opportunities into goals while allowing its opponents to convert only 50% of their opportunities. On the far right are details about how a team's Offensive and Defensive Scoring metrics would be expected to convert into wins and losses (as per the Win Production Function estimated in this blog) and how the actual win and loss performance of each team has compared to these expectations. After just one game, these metrics don't mean much, but they will mean a lot more as the season progresses.

Lastly, at the bottom of the table is information about the quarter-by-quarter performances of each team. Adelaide, for example, has won 100% of its 1st, 2nd and 4th terms, but 0% of its 3rd terms. Its percentage in Quarter 1s (points scored divided by points conceded multiplied by 100) is 308, and in Quarter 3s is 51. Note that the 4th Quarter rankings of all teams are currently undefined because Sydney has yet to concede a point in final terms.

These quarter-by-quarter statistics also don't yet mean much after a single round, but will become more interesting and relevant as the season progresses.
