One of the questions I have tinkered with off and on is trying to gauge the level of quality of different domestic cricket competitions. My limited research so far suggests that Australia's domestic level in first-class cricket is very high, and quite probably higher than some Test series between weaker sides.
On the surface, the T20 Champions' League might seem to make an easy job of it, but the number of matches played is so few that I would be very wary of using it as a barometer. However, the more of these competitions played, the better we'll be able to make judgements. What will be particularly of interest this year will be whether Indian sides again fail to rise above the mediocre level.
