Root does not have to captain at all. Anderson can
Root at 3 makes sense and it’s got to be Bairstow at 5 if that means giving up the gloves fine
I don’t see why Root has to be skipper? Why?
Because he is the man selected by the powers that be.
It is that simple. Whether he is the best man for the job or not is at this stage debateable - he has shown some flashes of creativity, and has handled a difficult tour with great dignity (which lets face it is more important to the ECB bigwigs). Yes, it has had some effect on his batting, but in that regard one would simply be shifting the impact.
It certainly shouldn't be given to Anderson. Eek out what is left in Jimmy's body, but don't make him skipper. Its not a role that works for quick bowlers, and he is now very seperated from most of the squad in terms of of age and interests.
If not Root, it should be given to Bairstow - who has a good cricket brain, and is plegmatic enough that it would probably affect his performance less than anyones.
