The point is that depth of pitching is not as important if you have one elite pitcher. The winning WCWS team will be the one that has a Top 5 pitcher in the nation. The backups are primarily irrelevant at the WCWS.
Totally disagree.
Yes, one of the WCWS teams will likely have a top 5 quality pitcher, however they will also have a top 20 quality pitcher who saves her b**t at least once at some stage.
And if you don't get that you either kill your pitcher (I don't think Nunley has recovered from last years abuse) until she is left with nothing in the tank and the hitters start smacking her around or you just don't make it.
