Much has transpired in the world of soccer statistics over the past four years since I first published: Possession with Purpose – An Introduction and some Explanations.

• Three years ago I published my Possession with Purpose – Revised Introduction.
• In 2014 the concept was presented at the World Conference on Science and Soccer 2014.
• Last year the concept was published in Europe and just this year another part of Possession with Purpose was presented at the World Conference on Science and Soccer 2017 (Predictability).
• Now it’s time for a new update that hopefully brings more clarity and simplicity?

• The .pdf version should make it easier to print and use as reference material.

Within you’ll find:

• Definition of TSI
• Purpose of TSI
• Premise of TSI
• Parts of TSI
• Leagues / competitions analyzed
• Application of TSI and its parts
• The data for leagues / competitions analyzed
• Observations & conclusions by league / competition as well as reviewing TSI across leagues / competitions

My thanks to all for your support and kind words throughout the years.

In Summary:

• The sum of the parts has greater correlation to points earned than the parts independent of each other.
• Player A, from Team A, within any given league, has a different correlation to points (performance/outcome) than Player B, Team B, Player C Team C, etc in that same league.  In other words outcomes of individual player statistical analyses are NOT EQUAL from team to team and league to league.
  • • Said differently, clearances or crosses (used as a measurement in fantasy soccer) for one player, on one team, DO NOT have the same weight/value of clearances or crosses for a different player on a different team.
    • Same can be said for passes or shots taken, etc.
    • Therefore, Calculations such as Expected Goals are not an apples to apples comparison between teams within the same league.  Yes, it’s a predictive tool, but flawed/
• The lower the overall correlation of the Total Soccer Index to points earned the greater the parity within the league or competition; this also intuits those are less predictable.

Best, Chris
