So, over the last 15+ years we have Bosio (pretty good until hurting his knee after leaving Milwaukee), Wegman (average to slightly above), Plesac (awesome closer for a short stretch, after which he became a solid set-up guy), Eldred (incredible rookie season, followed by not ever living up to hype), Navarro (couple pretty good season followed by being terrible), Sheets (awesome if he can get over the injury bug of the last couple of years). That's pretty much it other than one terrific year by D'Amico. No idea how that stacks up against other teams, but Milwaukee has to be close to the bottom at bringing successful pitchers up through their system since 1990.
