I think the FO (i.e. Whaley) has the tendency to pick players with borderline injury histories. We've seen this with numerous picks, as well as free agency. We want to point our fingers at the medical staff, but they are not the ones drafting our players. Many of these players come with well documented injuries. At the end of the day, Whaley has final say and he has been selecting them.
If we had selected Gronk, who came with a clear injury history, would we be calling for the medical staff to be fired? He's injury prone and this is why the majority of teams avoided him. If Whaley was in charge that daft though, I'm sure we would've taken him.
What exactly was our medical staff to do with Henderson? They deal with sports medicine. Were they supposed to guide his Crohn's treatments? I'm glad they were hands-off in this situation. His disease is completely unrelated to football, so their hands were tied. Let him come back when he's ready. They played this one correctly.
