Regarding the overall league offensive environment, I think it’s less injuries/depth and more to do with putridness of CWS and MIA offenses, with COL not much better. Those three are wRC+ of 62, 67, 75 respectively. Most years shake out with the worst team around 80.
FYI the Os are currently 127 wRC+ only trailing the LAD 128. Also note that Os are second in BSR, only trailing CIN, with CIN, Os, KCR significantly better than rest of league.
