7 years ago was 2019. Roman, Mayer and KC hadn't even been drafted yet.
They weren't dumping Mookie and others "to make room for prospects." They dumped all those players because they didn't want to pay large salaries anymore (and still don't). Do you consider Franchy Cordero a homegrown player, because that's the type of player they ran out from 20-23? They youth movement didn't really start until '24 with Rafaela, Abreu, Duran, Bello given fulltime roles and some extensions handed out. That was all under Breslow.
