With no football to entertain us, football analytics nerds got busier than ever in this quarantine period: Metrica Sports released high quality full match tracking data,

 and his Friends of Tracking have been releasing incredible work every week, and Seattle Sounders organized an online conference with some of the biggest names in the analytics world (and also the COVID “death charts guy”).

But even with increasing availability of tracking data, the most valuable work in football analytics is still — and will continue in the foreseeable future —being done with events.

Therefore, one of the most important outputs of tracking data analysis is to improve the definition and richness of events.

Indeed, codifying and recording events is hard work, and sometime not even that objective.
