Event data has proved useful to many clubs, in particular, in scouting players. The best-known statistic in this context is expected goals, which measure the quality of chances players create. Other more advanced metrics include expected assists, passing models that assign a value to every pass based on how much it progresses the ball, and possession chains which measure involvement in attacking sequences. These stats, along with more traditional measures, such as tallys of heading duels, interceptions, and pass completion, are often presented in the form of a player radar. The radar shows how each player compares to others playing in the same league.
To measure the quality of a team’s draft, he used Approximate Value, a system that assigns a point value for every player’s performance no matter the position. In contrast, many highly touted high school players flop at the college level. Over a recent 5 year period, only 42 of 316 college players named to All-American teams arrived on campus as 5-star recruits.
Data were collected, cleaned, transformed, and aggregated from non Gamstop betting sites from over 20 tables. Various predictive models were used to create an accurate predictor system. Players were chosen from top Football/Soccer leauges like Premier League, La Liga, Bundesliga, Serrie A, and Ligue 1. The final dataset had over 350 players with detailed statistics parameters of performance collected from over 2 seasons. “On the other hand, an ever-increasing number of clubs is leveraging data by collaborating with specialized companies that offer data-driven tools for opposition scouting and player recruitment. For instance, SciSports offers an online platform that helps football clubs identify potential transfer targets in a matter of minutes with only a few mouse clicks.
In a last-ditch effort to find skill, Paine looked at how a 3 year period of one GM affects the next 3 years of his tenure. This restricts the data set to executives that survive for 6 years, an eternity in the modern NFL. This data shows a weak correlation, which does suggest a tiny amount of skill in picking players. Bill Barnwell of Grantland asked whether turnovers forced in the first 5 games can predict turnovers forced the remaining 11 games. Over a huge sample of more than 600 NFL teams, he found no correlation between early and late season forced turnovers.
There are no particular tools or software introduced in this course. However, at the end we do link to some of our existing resources for getting started with data (especially our R/python packages). With that out of the way, let’s dive straight into the top 6 football analytics metrics you should know about.
Adding up a player or team’s expected assists gives us an indication of how many assists a player of team should have had based on their build up and attacking play. The idea behind xG is to accurately depict the prowess of the shot taker. And here’s what I want you to take away – you should not judge a player based on his xG per match. This is a statistical metric – which means it will vary from match to match. The Expected Goal metric, or xG, tells us the likelihood of a player scoring a goal based on the situation he/she is in.
XG assesses every chance to give us the probability of a shot finding its way into the back of the net. It can sound intimidating to a person who’s been watching football for a decade or two . You feel you’re being left behind and that these “nerds” should leave football to the romantics. That feeling you get when you watch your team week in week out, the anguish of losing and the ecstasy of winning – it’s all part of our romanticism of this beautiful game.
