Will Vaughan Make a Difference?

The Question has to be: Will Michael Vaughan make any difference to England's current run of bad results. Vaughans personal form in ODIs is not great, averaging a mere 28.36 and Englands form in ODIs over the last year has been pretty pathetic. So I predict that he won't make any difference for the one day series in Aus and the world cup i.e. no semi for England. However the Test scene is definitely his saving grace. England play West Indies and then India at home. Both teams are known to be bad tourists especially in England and they are going to make Vaughan's year.
