The rebel tours occupy a contested place in cricket history. The straightforward defence offered at the time by participating players — that they were professionals making professional decisions, that South African cricket was being unfairly punished for its government's policies, that sport and politics should be separate — has not aged well. The contemporary cricketing assessment is closer to that of Mike Brearley, who declined to participate in the 1982 tour and wrote afterwards that the rebel tourists had "lent their professional credibility" to a regime that depended on demonstrations of normality to maintain itself.
The tours did, in one specific sense, fail in their primary purpose. They were intended to relieve the cricketing pressure on South Africa, to demonstrate that the international ban was porous and that South African isolation could be circumvented. Instead, each tour intensified rather than relieved the pressure: the political reactions in England, Australia, Sri Lanka and especially the Caribbean strengthened the international consensus against apartheid sport, and the disruption of the 1989-90 Gatting tour by South African anti-apartheid demonstrations became a public symbol of the regime's collapse. Within months of the Gatting tour's cancellation, F.W. de Klerk had announced the unbanning of the African National Congress and Nelson Mandela had been released; within fifteen months South Africa had returned to international cricket through the front door.
For the players who participated, the legacy is personal and varied. Some, like Gooch and Emburey, eventually rebuilt their international careers and have spoken publicly with regret about the choices they made at 30. Others, like several of the West Indian rebels, never recovered. The most enduring lesson of the rebel-tour era for cricket administration was that the financial offers used to break the boycott had been possible only because international cricket was so under-paid. The rapid development of central contracts, professional player associations and competitive limited-overs television rights through the 1990s and 2000s was, in part, a response to the lesson of the rebel tours: that players who could be priced cheaply could also be priced away.
