Bush vs. Parra: Why the Brewers messed up

Like most Brewers fans, I was stunned Sunday afternoon. First I have to sit at Miller Park and watch our offense not do much of anything and lose a tough game in 10 innings. Then, as my buddies and I were driving home, I heard Breaking News. The Brewers were optioning Dave Bush to Nashville. No, not sending Manny Parra to Triple A or cutting ties with Derrick Turnbow, but sending a quality arm to the Minors. I know many fans are fine with this move as many have given up on Bush's ability as a starter. I, however, think this is a grave mistake by management.
