 This system has been abandoned for 2017–18 and beyond in favor of a six-team playoff system identical to that currently used in the Top 14, with only the Pro D2 champion earning automatic promotion and the runner-up advancing to a promotion/relegation playoff with the second-from-bottom Top 14 side.Previously, the pure Shaughnessy system had been used to determine the Top 14 champion, but that league's playoffs expanded to six teams starting in 2009–10.The Super League in rugby league, made up primarily of English sides with one from France, adopted a Shaughnessy playoff beginning in 2015.
