The concept of players fulfilling specialist roles isn’t a new one when looking across international sports. American sports such as football and basketball are perhaps the most obvious examples. American football has specialist kickers and even special teams squads. In basketball dependent on the game situation it is common to see coaches rotate players on an offence, defence basis. Closer to home, rugby has progressed to the notion of finishers rather than substitutes, a sign that players who are not stating will come off the bench to fulfil a specialist role.
