Timeline of Boucher's stint - some success, some failure, a lot of drama
He will step down as the South Africa men's head coach after the T20 World Cup, bringing an end to an eventful stint of just under three years
In a frenetic few days before England visited South Africa in December 2019, Graeme Smith was named South Africa's director of cricket, and he chose Boucher as the men's head coach. That followed a tumultuous few weeks in South African cricket, in which the chief executive Thabang Moroe was suspended amid allegations of misconduct, and the administration was overhauled.
Regular captain Faf du Plessis was rested for the ODI series against England, which took place just after the Tests. Quinton de Kock was appointed stand-in captain, soon after which du Plessis stepped down as Test and T20I captain.
Boucher said - and explained why - South Africa wouldn't take a knee during their white-ball matches against England in November 2020. That opened a Pandora's Box of sorts, and South African cricket's relationship with racism, in general, and the Black Lives Matter movement in particular. Eventually, almost a year later, the CSA board issued a directive that the team would have to take a knee at the T20 World Cup.

South Africa were seventh on the ICC Test rankings table. Their Test resurgence began with a 2-0 win in the West Indies. However, they soon lost an ODI against Ireland for the first time in their history, dropping points on the World Cup Super League table, before also losing a series in Sri Lanka 2-1.
South Africa narrowly missed out on a semi-final spot at the T20 World Cup in the UAE, hurt because of their poor net run-rate. The tournament was overshadowed by the CSA board directive to take a knee, which de Kock had initially refused to do.
On an all-format tour of England, South Africa squared the ODI series 1-1, won the T20Is 2-1, beat Ireland 2-0, and then won the opening Test at Lord's. But they lost the Test series 2-1. They were shot out for their lowest total - 118 - in England in 110 years in the deciding Test at the Oval.
