How good was england's last 5 one-day series?

I think England's performance in the series against SA was very good. But, don't read too much into it just now. For currently, the zeal of a new captain and the fact that SA were already sick and tired of travelling might have given England and easy outing. The real test lies ahead at the Ashes. Of course, this Aussie side sans two of England's biggest tormentors - Glenn McGrath and Shane Warne. But even then Aussies would be the real test for the English boys. Cheers! Ram
