The Sky is the limit: introducing the Aerial Spatial Impact Rating (ASIR) A data-driven look at why traditional aerial dominance is an analytical dead end

The Sky is the limit: Introducing the Aerial Spatial Impact Rating ⚽️📊

Using correlation we can see that there is little predictability between traditional aerial dominance metrics and points per game. With ASIR, we have a higher correlation.

Every season I take one specific league, watch majority of the games, release all my data analysis + engineering on that league and create models/apps.

Best thing I've done to get to know the league on a deeper level. This season? Portugal 1st tier.

You beat me to it haha! I'm writing an article, where this is included as well - although being my own model to evaluate quality, but yes. I really think this is very interesting.

Here’s the top 20 players in those five leagues for quality of throws into the box in the last 12 months. Note how some clubs are really leaning into it (Brentford, Hoffenheim, Parma, RBL). Kayode is also second for volume of throws into the box per 90 in this period

Is the long throw-in making a comeback?

It seems that the Bundesliga was early on the trend that's happening in Premier League now, but the Premier League has seen an explosive growth in long throw-ins.

La Liga, Ligue 1 and Serie A don't seem to take part in this particular trend.

First time really scouting U20 world cup, fun times ahead.

Living with depression is life disrupting, debilitating and cruel. Constantly fighting with and against your own mind.

It’s okay to not be okay. It’s equally okay to be okay.

You’re enough. You’re loved❤️

Interesting point. I don't have the data on this at hand, but I feel this also is happening in the Eredivisie and as a consequence the quality of the league is shifting from a distinct top-mid-bottom quality to a top-bottom quality, the extremes rule.

The longer I work with raw data, the more I realise how many biased decisions are made. Which isn't inherently bad, but how we should always be aware of it.
