Just speculating (a/k/a talking out my ass) like everyone else, but I remember when Jose Vizcaino left there was some talk that he'd be a manager some day, and mutual talk that maybe he'd end up back in the Houston organization. Anyone know where Viz is now, or what he's been doing since he retired, in 2006 I think?
Or, if it is someone with prior experience they want, what about former Astro Davey Lopes? He didn't do very well in Milwaukee, but he didn't have a lot to work with, either. Hiring him would continue the Brewer connection (Garner, Cooper, etc.) Drayton could still feel good about himself morally, and keep Selig off his ass. Plus, you are supposed to follow a manager with a, well, laconic style with a fiery, hands on guy, and Lopes is that.
Apropos of nothing, I've noticed no one ever brings up Dierker in these scenarios anymore.
