I agree that we need a big time pitcher. No question about that.
Yet Hofstra and South Florida made the Supers this year (granted South Florida had help because Florida's off the field issues helped implode the team), and there's no reason to think the Super Regionals are out of line or an unrealistic goal for this team in the future.
The thing I liked the most about this year's Irish is that it seemed that they had confidence in themselves, and they acted as if they belonged on the same field as Arizona. That's half the battle - believing that you belong there.
By the way, I've been watching the WCWS for over a decade, and I don't need a lesson on what excellent pitching looks like :-)
