Rugby's data revolution - can Moneyball be oval?

"I've watched more rugby in the last five years than I think I'll ever watch in the rest of my life."

And for Angus Campbell, that really is a lot of rugby.

On a weekend, Campbell will gather with his Oval Insights colleagues in an office on an industrial park outside Leeds and watch live feeds of games happening simultaneously around the world.

It sounds like a sports bar. It is, in fact, hard graft, as they harvest data at scale.

For each match, two people work furiously to categorise the main elements of the action as it unfolds, marking possessions, penalties, set-piece outcomes and open-play kicking.

Another four people follow behind, taking passages of play in turn, and enriching that initial information with finer detail.

Individual carries, post-contact metres, tackle success, tackle type, tackle dominance, individual ruck entries and ruck duration are just some of the information they are hunting.
