The unofficial arm of the Boston Red Sox, a.k.a. The American College of Radiology has scientific guidelines on the use of imaging in the diagnosis of rib fractures. Really.

So what we don't know are 1) the facts (how completely Jacoby Ellsbury has recovered) or 2) the context, as in are there other factors souring the relationship between Ellsbury and management. Throw Scott Boras into the mix, and we get more heat and no light.
So we lack the facts and have too many 'beliefs' based on just about nothing. So what else is new?
