At least for an offseason and into 2006 as the Rockies have invited the entire coaching staff back (link from the official Rockies site). This is from the Thomas Harding article:
"I believe in stability, but I believe in holding people accountable as well," Hurdle said. "I want coaches that make a difference. I tell players that doing OK is not good enough. I can't have a coach that is just doing OK. We can't have a manager that is doing OK."
There are definitely fissures occuring between O'Dowd and Hurdle and I wouldn't be surprised to see one of them gone by midseason next year if we start off as badly. Evenso, I think at this point we have to be looking for a midseason change to occur unless we really see some significant improvement with the players. If Hurdle goes, most of the coaching staff will likely go with him.
