Future Ideas

  • Visualize difference between proportion of the EPL season in which a team is in the top 4 of the league with matchweeks vs. actual time.

  • In which sport is the leading team most likely to further their lead near the end of the game due to an opposition error, overly-aggressive tactics by the opposition, etc.? (End of game depends on the sport. Ideally, we could use a win probability model to help identify end-of-game context, although it would still need some adjustment.) Extension: In which sport are gamblers most likely to lose/win due to a back-door cover?

  • Decision tree to filter down players in a sport to just one player who has achieved a very specific set of career totals/averages (i.e. inspiration)

  • Playing time in career at current team sonar (inspiration)

  • Which positions is it ok to have a weak spot at? (inspiration)

  • Do coaches sub-off players with yellow cards at a higher rate than they would otherwise?
