Palmer had a history of shoulder trouble as didnHalladay.
Drysdale was from an era when pitchers threw 25 complete games. It is a wonder that any of those guys made it to 30.
Should have left them both alone. Pablo was already on a steep decline and Hanley was damaged goods too. Never mind that there was no place on the field for both of them. They should have put the money toward Scherzer.
