That's the problem here though. The players here were all complete question marks whether health related or defensive prowess. Duvall is a corner outfielder playing out of position in center. Acquiring an oft-injured in Mondesi who on top of the ACL injury had trouble staying on the field in prior years. They knew Story had issues with his elbow to the point that he had to play 2nd base so when asked to play SS he immediately gets hurt again trying to get his arm ready. These issues should not have been a surprise to anyone.
I was responding to Duvall being "poor outfielder." Not really. In CF or anywhere else in the past. (If I'm missing something that says Duval was a bad OF -- or a bad CF -- in the past, show me. I haven't found it.
Or Hernandez (not poor at SS or anywhere else). Again -- show me because I can't find it.
Absent something that suggests that the bolded was true in, say January, those really aren't question marks in any legitimate sense of the word.
Mondesi was a risk, so they got Chang in ST, who was doing the defense job that Hernandez could not do, until Chang got hurt.
As for Story, I am inclined to believe that getting ready for SS pushed his elbow. But I am also inclined to believe the reports that finally getting it fixed will get it fixed.
