Whilst all types of cricket can see matches flip favourites in a short space of time, I think that it is more difficult to turn around 20/20 games than 2 innings formats. Similarly, some improvisation e.g. Zaidi going up the order, makes sense but looks poor if it doesn't come off. Problem is, you begin to wonder whether there is a definite gap between us and teams who win trophies.
This was the case in the 1970s when we'd look favourites then fall apart at the end of the season. Back then, it was deficiencies in key departments (we had to wait until the triumph rate of Hardie, McKewan and Gooch hit consistent form) as well as a collective naivety (I.e. No one in the team had actually won any trophies until Denness came along). There's clearly comparisons with the first point nowadays (won't repeat here) but not with the second - which is very frustrating. However, looking at the ages of our trophy winning senior pros, that is a problem.
