Superstats is ESPNcricinfo's new bouquet of stats metrics for enhanced and in-depth storytelling. It consists of three elements:

Smart Stats goes beyond runs, wickets, averages and economy rates, and values player performances based on opposition strength and match context. Read more about it here, and check out the Smart Stats results from IPL 2018 here.
Luck Index is a unique metric which, for the first time in cricket, quantifies every lucky event in a match, whether it be a dropped catch or a poor umpiring decision. Read more about it here.
Forecaster does a spot of crystal-ball-gazing and predicts win probabilities in each game.

Through IPL 2019, ESPNcricinfo has been doing match analyses using these tools, to provide greater insight and more in-depth stats-based stories from the tournament. Here is a list of these stories:
