Pure speculation on your part.
There is zero evidence that anyone on the Angel coaching staff or the medical team is at the root of the pitching injuries...none!!
It's just like the whole Mickey Hatcher thing. Everyone wanted to blame him for the hitting woes but nothing got any better when he was fired.
This bs has started to take on a life of its own, something similar to blaming Scioscia for any of the other Angel problems.
If only we'd get rid of Scioscia and the pitching/medical staff all of the Angel problems would disappear and the next stop will be another WS championship..if you believe that I've got some property in Florida that might interest you.
YMMV
