GMU - Pettite was a big piece that series, but I think he was 3d starter on that staff. he won some huge games, IIRC, in the world series.
You can say a rookie shortstop, a rookie big rotation piece, and a sensational set up man. I'm not sure about Bernie. But the bulk of the position regulars, and the other rotation pieces, all had playoff experience, plus I think the closer.
