There was a time in rugby union when the phrase “Bomb Squad” felt novel. South Africa were ahead of the game in maximising the impact of replacement forwards off the bench and the sight of all that fresh beef rumbling on to the field early in the second half was certainly arresting. As the Springboks have proved repeatedly, it works a treat if you possess the requisite strength in depth.
As with all good ideas, however, other people love to copy them. And so we have a modern-day arms race. Everyone now has, or aspires to, their own Bomb Squad. Around the 45th-50th minute in virtually any game there will be an army of stunt doubles preparing to replace the players who started the game. And if a coach can field fewer than three specialist backline reserves in order to bolster further his forward resources, happy days.
