Former Irish hooker Keith Wood supports World Rugby's potential law change to lessen the impact of the scrum. The proposal, to be voted on in May, includes preventing teams from opting for a scrum after receiving a free-kick. Despite criticism, particularly from South Africans, who view the scrum as a key weapon, World Rugby hopes to speed up the game. Wood agrees, emphasizing the need for quicker scrums to focus on winning and moving the ball. He also suggests reducing the number of substitutions during a game to enhance the sport.
