If the Reds are out of contention to the point of trading Votto, why would they be considering Miley?
In the same vein, Colin Rea is 33 and a career negative WAR pitcher. I know they shouldn't expect much for Votto, but if they're going to literally get a bag of nuts for him, why not just ride out the season, and sell some tickets and jerseys?
There's no value to the Reds with guys like Rea or Miley in the short or long term future if they're not contending, so this makes no sense.
