Primarily, The FO constructed this team, failed to acquire a deeper relief corp, failed to sign better hitters, failed to offload/DFA Gallo, and failed to make trade deadline deals to fix the glaring weaknesses or improve the team for the future.
secondarily, Rocco has stuck with Buxton and Correa at the top of the lineup even though those two are the worst hitters on the team, and Popkins has failed this team as a hitting coach. These are incremental adjustments that mitigate the damage that the FO unleashed upon the roster.
it’s not the pitch clock’s fault if the players can’t/won’t adjust. It’s the players
the “separation” policy seems more like a dearth of mid-bullpen reliability. There’s three trustworthy relievers and the rest are bad. If the bullpen had been addressed by the FO, that “separation effect” would be less noticeable.
