Like Bavuma, Proteas captain's cauldron dawns for Elgar but can he claw his way out of slump?

There is a certain kind of pressure that is the pure preserve of a Proteas men's captain.

It's nothing like a Springbok, Bafana Bafana and other sporting code skippers experience. It can be dark and vicious and, once it descends, proves difficult to shake off.

It's a dungeon where Temba Bavuma lived for two months during his off-colour T20 season up to and including the T20 World Cup in Australia, where calls for his head were a daily occurrence.
