Amla has to be a shoe in (the other two great batsmen of the year, Clarke and Cook, have won it before) and I suspect that Steyn and Compton will be considered as well.
Ajmal might be hamstrung by his lack of impact on the English season, which is the theoretical marker. In any event, I wonder if Vernon Philander might get that slot, given that he made such a remarkable start to his Test career and that he was influential in the Yarpies getting to number one....
Kohli, no. If there were to be another overseas batsman, I reckon it would be Mike Hussey. Done very well in tests in the last 12 months and has been very close to an award in the past.
If we go back to the county slot you've given to Compton, I reckon that they usually go for a key player from the champion county, which to my mind opens the door to Chris Wright being a surprise winner.
Finally, given their continued success, I wonder whether or not we might see another female winner. Most probably Sarah Taylor?
