Left field choice here, but I'd go with Stokes. He has a great attitude on the field, he won't be bullied by anyone, he knows when to be aggressive and when to be more cautious, and he just seems to have that nous that a good captain needs to be successful. Admittedly he's inexperienced in test cricket, but with the way things are at the moment, that's something we can't afford to be held back by, especially as he looks like being the one bright spot from this utterly shit series.
Time to build for the future and pick someone who will thrive on the spotlight of captaincy rather than be held back by it.
