Much has been made in recent weeks of La Rochelle’s Keep Ball Alive philosophy since head coach Ronan O’Gara mentioned the phrase in an interview.

It even has its own three-letter abbreviation. The idea is that by adopting KBA strategies, the Rochelais stretch opposing defences enough to create scoring opportunities for their backs, who are - to a player - PDQ (pretty damn quick).
