Why did you dock him 50 runs?
I suspect he gave up captaining on Sunday when Stokes and Bairstow were going bananas and he looked completely lost in terms of ideas how to stem the runs or in terms of how to motivate his team. Mind – There’s a few might have struggled with that at that time.
From thereon – his mind was clear as he knew he was jacking and all he had to do for himself and for the team was to bat and bat. And bat and bat. And then bat some more.
At that point – he’s free to do what he is bloody good at unencumbered by worrying about anything else.
Captains who can compartmentalise captaincy from their own game are very few and far between.
