Billy had two acceptable years as a starter for the Reds. Everything about his time as a Red screamed he was a role player that they Reds FO couldn't push out of the starting lineup simply because they weren't creative enough. Literally from 2013-2018 there were 29 qualified center fielders who were more productive based upon WAR than Billy. KC is a dumpster fire at the moment and it barely took them a little over half a season to push Billy off their stinking 25 man roster and that's an organization that is gagas over speed and defense.
So yes, that Billy was a 5 year starter for the Reds says a ton about the deficiencies with the Reds.
