Injuries are 1 factor you can't really factor in when negotiating contracts.
Also, Woodley's contract become untenable because of the cap situation and the continual restructures performed by the FO.
So, IF Woodley doesn't go down against the Pats* and stayed healthy. And IF the FO kept their act together, we all would have a different opinion on Woodley.
For the injury, you can blame conditioning, maybe.
For the way the numbers got crazy, blame the FO.
