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.

Task: Take a league/leagues and just try to create as many possible new visuals -> you learn a lot about the league too!

Match simulations: NK Varaždin - Dinamo Zagreb

Expected Shot Danger: can we find a hybrid shot model that has a Location Quality Score + Outcome score?

I wanted to measure threat away from xG, but not make an alternative to xG. Looking at Ice Hockey + Baseball analytics to enhance it.

Full article + methodology tomorrow :)

I have created a GK Value-model that has values for Shot-stopping, Distribution, Leaving Line and Ball Handling. It's still a WIP, but I really want to see if we can use the current available data (which is so little for GK!!) to analyse GK match performance and beyond.

Fortuna Sittard - Go Ahead Eagles 2-2

Eredivisie is back! Fortuna were better in that second half, creating chances after red card - but never rule out a set piece goal: GAE really did well in that regard.

Working in NCAA D1& D2 Men and/or Women? Let's connect!

For research I'm looking into how these programs use data in recruitment, analysis and set pieces. I'd love to have a conversation and share thoughts.

DMs are open or email me: waltzinganalytics@gmail.com

We tend to focus on absolutes and and hold people to that standard. Shaw's 24-25 season wasn't good bc she didn't replicate 23-24 season, or in this case: Beth Mead.

Not topping charts, doesn't mean you are not good or impactful. Mead is still a huge goal threat.

I wanted to find meaning in shot-based value models away from expected goal. Based on Ice Hockey analytics, I had a look at Fenwick and Corsi data. On that I created a few new metrics to value possession in combination with shots, rather than likelihood of a shot -> Goal (xG)

Van de Donk will still be immense in the WSL, and I think the impact she will have at a club outside of those trying to get into UWCL/trophies will be relatively big.

Slightly ironic of me talking about xG, but looking at how "good" my model is, I know I still have to look what can be improved. Good to be aware of that.
