I don't know if that would really hold up to scrutiny. I'm confident if we went back and read all the list posts from '08 and '09 Charlie seemed just as stupid (and was!). Just for different reasons.
Not sure there is an empirical reason why it's bad to use more pitchers, other than, it's not fun to watch. Overuse, yeah, but I don't think that's an issue this weekend.
Meanwhile, the Nats have a bad bullpen too. C'mon! Wow, so close by Rodriguez there.
