Impressive list.
I would look at viewing figures though, say viewing figures for the biggest game in NFL and the biggest game in football so the World Cup Final or the Champions League Final.
FIFA World Cup Final Beat Super Bowl LVI By More Than One BILLION Viewers In TV Ratingshttps://www.si.com/fannation/soccer/futbol/news/how-fifa-world-cup-final-beat-super-bowl-lvi-in-tv-ratingsPersonal opinion - Not that many people outside of the US care about American Football.
Football (soccer) is undisputedly the most popular sport in the world and it’s not even close.
Add the biggest game in cricket India vs Pakistan to the list as well.
