Well, it remains to be seen whether he'll be any good or not but I am more excited by the prospect than I was by Cook's appointment. I really hope that he can show the same calm, steely aggression that he does when he is batting well. I'm hoping he will be less predictable with field placings and declarations!
These days, where anyone looking like a good international prospect is wrapped in cotton wool and only really plays for the national team, it is unlikely that any candidate is going to have any real experience of captaincy, either a batsman or a bowler. Learning on the job will be tough but hopefully the management will support him well.
