One win does not answer all of the doubts, twenty years of embarrassment on the biggest stage of all so we should not go overboard after one win. Cook had barely anything to do, he was dismissed cheaply, it was however an encouraging start and one he desperately needed.
Oh god, I'm agreeing with Crodo. While it was a very good performance from pretty much everyone (with the possible exception of Cook and Bell failing with the bat) I still think there are issues with the balance of the team; it was hidden here by Jimmy's excellent bowling/fielding and a good batting performance but I'd like to see at least a sixth bowling option in the team, if just to provide a bit of variation.
