I disagree about Dombrowski being accountable for players who get injured. As I've said many times in my defense of Ben, the GM's job is to assemble a team who, on paper, is a contending team. I realize that what a team looks like on paper does not always transfer to the actual games, but the GM cannot control what happens on the field. In terms of the team assembled for this year, Dombrowski did a great job.
That said, if there was something in the medical reports or the FO was not diligent in screening the health of these players before they were acquired, then we're talking a whole different story. Pomeranz' health questions remain to be answered.
In terms of Smith and Thornburg, I think it's just bad luck.
