One really bad thing about last year was that many of the injuries happened at the same time at like positions:
Story and Arroyo went down at the same time, which forced Downs, Sanchez, Arauz and others to play 2B. (Kike might have been an option at 2B, but he was out, too.)
I think 4 of our SP'ers were all out at the same time, and 2-3 were out, together for long periods. Of course, we knew Sale and Paxton were starting the year on the IL, but we lost Wacha, Nate, Hill and Whitlock/Houck for much of the same time periods.
The weakest area of the team, the pen, might have been the healthiest, although Houck, Whitlock and Barnes missed time. (Taylor missed the whole year.)
