The captaincy has been somewhat of a poisoned chalice for past English all-rounders. Ian Botham and Andrew Flintoff’s brief tenures in the role are the obvious examples. Despite being dominant performers, both were unable to transfer that dominance into successful captaincy. It is often said that the burden of captaincy inhibits a player’s ability to play. It creates a greater cognitive load and inhibits the ability to focus on their usual role. Is there any evidence to support this observation?
