LAWS: Andy Goode explains why legally Underhill’s try would have stood just 6 months ago

Offside lines created after tackle

Add new 14.10:

Offside lines are created at a tackle when at least one player is on their feet and over the ball, which is on the ground. Each team’s offside line runs parallel to the goal line through the hindmost point of any player in the tackle or on their feet over the ball. If that point is on or behind the goal line, the offside line for that team is the goal line.

This only came in play on May 16th of 2018.
