Losing Lynn, Gibson, and Goldschmidt makes almost no difference. In fact, the team is probably slightly better due to the progress of Pallante and McGreevey and the addition of Fedde.
Adding Arenado as a loss hurts some as the Cardinals don’t have an equal substitute. Call that a loss of 3 wins.
Adding Helsley to the list really hurts. That’s 3-5 more wins at least if he pitches again like last season.
So call it 7 wins. That puts the team at 76 wins +/- 5.
