Fielder was body / getting old / baseball related type stuff. You don't compensate for that. If he hadn't had the physical issues and had gotten in a bad car accident that had ended his career, that might be different.
We'll compensate Cyborg in the BBDL as well for JF (not that he probably needs it), just as we did for P2F and Taveras. Given that this happened at the end of the season, whether that compensation happens for the 2017 draft or 2018, I don't know.
