I don't want Warthen back. The whole thing about trying to shame our SP's into throwing strikes really bothered me. Bones is credited with doing a lot of good things especially for Niese so that's why I like him. I'm not sure who our A/AA pitching coaches are but Alderson is going to have a lot of info to go through.
And on the manager, I really don't care. The Alderson philosophy (if it hasn't changed) is basically that the manager is basically just an extension of the front office. So he'll play the matchups, not makes too many moves based on his gut (like Jerry), and not give away outs. It'd be tough not to get on board with a fiery guy like Backman if he was willing to be this extension, but I'm fine with whatever.
Don Wakamatsu is probably my favorite of the names we've seen come out though. Seems very cerebral and highly respected.
