First, the state of one-day cricket is such that pretty much any team other than Australia and perhaps now New Zealand (and of course outside of Zimbabwe, Bangladesh, Kenya et al.) have a 50-50 chance at beating their opponent. Teams like India, Pakistan, Sri Lanka, South Africa, England, and the West Indies are pretty much equivalent.
That being said, the West Indies are clearly, clearly the worst out of the six. Oh, but they won the Champions Trophy? Yeah, in the luckiest victory I've ever seen. That match should have been stopped for bad light hours before it ended.
But oh well, if you want to continue to foolishly claim that the West Indies are any good, go ahead. But just know that you're wrong to do so. They're a very, very bad team.
