Alastair Cook has been widely criticised for being too meek in the face of Australia's onslaught this winter but once the England and Wales Cricket Board confirmed it wanted him to continue as captain he responded by making the most ruthless decision of his career.
Cook is unworldly despite his travelling the globe these past nine years so he may not have considered the potential effect his decision to exclude Kevin Pietersen will have on his popularity as captain. If a poll conducted by Sky Sports this week was accurate, an overwhelming majority (88 per cent) felt it was wrong that Pietersen should have his contract terminated, an execution Cook had the power to stay.
Others will have balked at the prospect at facing the boo boys who will inevitably greet him next summer, but Cook is so steeped in his belief of the primacy of the team that he would not have considered his personal wellbeing for one moment.
He may look like a wide-eyed innocent but Cook is tough. You do not score more than 8,000 Test runs as an opener without being able to cope with brickbats and bouncers. With his faithful team-mates beside him he should be fine.
The best antidote to any woe in sport is winning and England have managed that before without Pietersen. Indeed, the batsman in possession of the highest average in England victories over the past 10 years is not the departing swank but Ian Bell.
Whether or not you agree with Cook's decision to end Pietersen's association with England it remains a courageous one even if he did not speak to him during the fateful meeting in London that decided the latter's future eight days ago.
While not against the outcome, my only dispute is whether England's captain was thinking clearly when he made his conclusions. Cook had been back home less than a week when the meeting was held. Emotions from a tour in which Australia pounded England in all forms of the game would have still been raw. Far better, surely, for him to have taken his decision after a month's rest on his farm. That way he would have at least known that head and not heart had made it.
It is a gamble by Cook. Australia was his first Test series defeat as captain but the feeble nature of the loss means this will be his final chance to make his leadership work. To take it on without your best batsman, albeit one who appears in decline, shows that he prizes team unity more than individual brilliance, though that does tend to be the English way.
Even so, Cook must still have felt betrayed by Pietsersen, especially after he had been the one who had pushed hardest for his reintegration following the text messaging scandal with South Africa in 2012.
Pietersen repaid his new captain's faith then with a brilliant innings in Mumbai but not this winter in Australia where a combination of soft dismissals on the pitch and hard words off it against the leadership trio of Cook, Andy Flower and Matt Prior, were considered destabilising.
This is where a more worldy man than Cook might have sorted it out.
The proliferation of coaches and management in modern teams means that players have become used to seeking solutions to their problems from others and not themselves. In the past, the team member with the biggest muscles would have pinned Pietersen up against the nearest wall and told him to behave. It used to be surprisingly effective and nearly every team possessed such an enforcer.
It is too late now and perhaps such a direct fix would not have worked on Pietersen anyway. His departure has meant the creation of a vacancy, one Eoin Morgan is eyeing following his withdrawal from the Indian Premier League auction which begins tomorrow.
There is a neat irony about Morgan's decision. Morgan knows, as Pietersen once did, that Tests are the format where legacies are made.
