McCullum must be held to account even if England end Ashes with another win

There’s a good origins-story-style video in the Sky Sports masterclass archive. Filmed at Edgbaston in 2016, it shows the blue-sky brothers, Brendon McCullum and Rob Key, back when the world was still young, looking sharp and chiselled, laughing and joshing on the outfield, and nominally discussing how to bat in T20 cricket.

And yes, the chemistry, well, the chemistry is overpowering. It almost feels like a romantic intrusion, the viewer cast as gooseberry. This is Coldplay kiss-cam energy. This is like watching Bacall and Bogart fall in love on screen. You know how to whistle don’t you, Keysey? You just put your lips together and enter into a transcendent game state.
