MAFL 2010 : Team Dashboard for Round 13

Sorry that this is a little late this week. I think I've been mentally recovering from the hiding that MAFL took last weekend.

Anyway, here's the MAFL Team Dashboard:

MAFL 2010 : Team Dashboard for Round 12

Here's the week's MAFL Team Dashboard.

This week I thought we'd take a look at the correlations between team ladder position and the performance statistics in the Scoring Shot Data and Quarter-By-Quarter Performance sections of the Dashboard.

Here's the summary:

Scoring Shots

• The (rank) correlation between Scoring Shots For (measure A) and Ladder Position is +0.75. It would be much higher but for the effect of St Kilda who are 12th on this measure but 2nd on the ladder.
• The (rank) correlation between Scoring Shots Against (measure B) and Ladder Position is +0.84.
• The (rank) correlation between the Scoring Shot Differential (measure C) and Ladder Position is +0.98.
• Creating and preventing scoring shots seem to be of roughly equal importance in generating success so far this season.

Scoring Shot Conversion

• The (rank) correlation between Own Conversion Rate (measure D) and Ladder Position is +0.72. Collingwood, who are 3rd on the ladder but an astonishing 14th on this measure, drag this correlation down. The Pies could surely have had no better reminder of the importance of converting opportunities than that provided by their 9.22 performance on the weekend, which cost them 2, and almost 4, competition points.
• The (rank) correlation between Opponents' Conversion Rate (measure E) and Ladder Position is +0.08.
• The (rank) correlation between Conversion Rate Differential (measure F) and Ladder Position is +0.41.
• Clearly, this season, success has been far more about converting opportunities than it has been about preventing opponents from doing the same.

Quarter-By-Quarter Performance

• The (rank) correlation between ranking on Q1 performance and Ladder Position is +0.79.
• The (rank) correlation between ranking on Q2 performance and Ladder Position is +0.58, dragged down by St Kilda, who are 2nd on the ladder but 14th on Q2 performances, having won just 4 from 12 second terms.
• The (rank) correlation between ranking on Q3 performance and Ladder Position is +0.69
• The (rank) correlation between ranking on Q4 performance and Ladder Position is +0.65. Two teams have depressed this correlation, Collingwood and Hawthorn, the former being 3rd on the ladder but 11th on Q4 performances, and the latter being 8th on the ladder but 16th on Q4 performances.
• Unusually, it's been Q1 performances that have been most indicative of a game's outcome this season. Winning teams have won first quarters in 71 of the 96 games played so far this season (and they've drawn 2 more), which is higher than any other quarter.
  To put this in some historical context, last season, winning teams won just 68.9% of games (ignoring draws). This season they've won 75.8% (ignoring the draw).

MAFL 2010 : Team Dashboard for Round 11

Here's the week's MAFL Team Dashboard.

A few things to note in this data:

• Collingwood, despite being placed second on the ladder, have the second-worst opponent conversion rate (56.4%) and a relatively poor record in final terms (which was starkly in evidence on Sunday night)
• Hawthorn are in the eight at least partly because they've prevented their opponents from converting opportunities in front of goal. They're struggling in the second half of games, particularly in final terms where they have a 1-10 record.
• St Kilda, Essendon and Fremantle are all allowing their opponents to convert too many of their opportunities. Essendon's struggles in first and last terms, Fremantle in third terms, and St Kilda in second terms.
• Relative to their respective ladder positions, Melbourne and Richmond are ranked highly on opponent conversion rate.
• Melbourne performs significantly better is third terms.
• Port Adelaide has mastered the art of the whirlwind finish, winning almost two-thirds of the final terms it's played. This hasn't been enough in 6 games out of 11 however.
• The Lions continue to pair lousy first halves with stunning second halves. The round just finished provided an excellent example of this, as the Lions were outscored 10 goals to 5 by the Roos in the first half of their game, before kicking 8 goals to 2 in the second half.
• West Coast performs relatively poorly in second halves.
• The Bulldogs are the best in the league for second terms.
