Cook could pressure Strauss
The ECB has taken the radical decision to go with three captains, across the three formats, with Alastair Cook taking over the reins of the ODI side from Andrew Strauss, who remains Test captain, and Stuart Broad as captain in the Twenty20 format
The danger to Strauss's ambition to lead the Test side into both Ashes series in 2013 is that the one-day side will flourish under Cook and so put the sort of pressure on his Test leadership that eventually caused Hussain to pass on those reins to Vaughan. It is a risk Strauss recognises, although the team would have to make massive progress for that to happen. Four series against subcontinental teams this winter and two at home this summer with the World Cup finalists will not make that any easier.
It certainly looks as if Flower will assume the autocratic role once filled by the single captain of old. If he does not, how will differences of opinion over who plays in each of the sides become settled? What if Cook wants James Taylor, the highly promising young batsman from Leicestershire, to play in the 50-over side but Broad does not want him in the T20 side? Flower will have to make that call, as he does already for Tests in collusion with Strauss, but you can see how it might quickly become messy.
Alastair Cook, England one-day International captain.
The interviewing panel may like to assume that in Cook they have chosen a like-for-like replacement for Strauss, a solid left-handed opener on whom more flamboyant characters can depend. But, for all Cook's impressive attributes, it would have been bolder to pick a more obviously accomplished one-day player, even a specialist unfettered by concerns in other parts of the game.
Broad will not have many games in which to lead before England have to defend their World T20 in Sri Lanka next year. But it is hard for a fast bowler to captain in any form of cricket – which is why so few do it at Test level – and in T20, where so much is happening so quickly, it may be harder still. As it is, both appointments look like an audition for the Test captaincy, which may easily now come up sooner rather than later.
I may not have much captaincy experience under my belt but I can honestly say I've always tried to think like a leader whenever I'm out in the middle: what fields I'd set, how to attack a new batsman, which bowlers to use - that kind of thing.
