Basically, he’s against it, and he thinks that it is more evidence of sloppy thinking by English management.
In my view, he’s quite right. England need to consider their long term as well as their short term goals. There has to be plenty of doubt about Vaughan being fit enough for a tough campaign in the West Indies for the World Cup, and lets face it, he’s not likely to make a difference to an English side that is chronically short of potent ODI bowlers. England’s batting is fine, it’s the bowlers that hinder them, in both forms of the game.
If Vaughan has any use at all to English cricket, it is by being fit and in charge at the top of the order, preparing for the 2009 Ashes campaign. Why you would risk him for the World Cup is an interesting question.
