Account of coaches' challenges and video review

We collect data about challenges by coaches, and the success of these challenges ever since the website's inception. However, on this page we show a more advanced metric - how often are these challenges, and not only them, but various video reviews, adjudicated, in favor or against the teams or coaches. We use both the data from the play-by-play files as well as the Situation Room blog. The data is available from season 2015 on. The data is available as an aggregate of a span. Currently we don't differentiate between regular season and playoffs.
