You don't believe it because it doesn't make sense?
I mean I don't have the story, you don't have the story, we don't have the story but that's a very plausible thing to happen. There are many, many different circumstances that would cause someone to lose a lot of weight. Could have been sickness, maybe he became sedentary when he was injured and wasn't consuming enough calories to keep weight on, maybe he was cycling on steriods and came off of it.
I'm not saying that's the root cause of his struggles, maybe it has nothing to do about it, but I don't think that's something you make up and then the Red Sox go along with and then corroborate that story. To me, that makes zero sense.
