I don't think it matters who the Captain is. Fair enough, it may make a difference in terms of how the team cope together and dealing with problems in the dressing room etc. But I'm sure where we'd all like to see a difference is with the match Tactics, i.e. Field placings and declarations etc, unfortunately for that, Cook is just an extension of the management. And with players having to buy into the management's philosophy through the Under 19s, England Lions etc moving all the way up to the Test team, I don't see it changing any time soon, no matter who the man in charge on the field is.
