I think you have to ... take an MRI on every pitcher that you acquire in a trade or free agency - the elbows, knees and shoulders. That's the only way you're going to be able to look at the elbow and shoulder and knees, and get a pretty good idea of what's in there.
I think that would be something that would get our attention for the future at least. Why not? That's the only way you are going to be able to look up in the shoulder or the elbow itself, have a pretty good idea of what's in there.
