The Cincinnati Reds have gotten younger, but have replaced defensive players with offensive ones. At nearly every position the defense has gotten worse than it was when the Reds last may their way to the playoffs. At every position the choice appears to be offense over defense, which has created some holes on defense.
The possible exception is center field where Billy Hamilton replaced Shin-Soo Choo at the end of the latest run. In all fairness though, Choo was the center fielder when the Reds were at their best. Hamilton’s debut in 2013 was when Choo was still the starter.
