The strategy is surprisingly sound, actually. Sign an upper echelon bat in Pollock, not worry about his health and use the Dodgers depth to either keep Pollock healthy or to replace him when he gets hurt. That works.
The Dodgers are essentially counting on Pollock to play somewhere between 110 and 125 games and players like Andrew Toles, Alex Verdugo, Joc Pederson and others will be there to play the rest.
Not to throw this word around lightly, but that is rather brilliant. When Pollock plays he maintains an OPS+ of at least 100 every year. Since 2013, in seasons with at least 75 games played, Pollock’s worst OPS+ is 100.
