Didnt see anyone answer this so I thought I would. From wiki "Morrow, who is a diabetic, acknowledged that his diabetes was a factor in the decision, saying that it was easier to balance his blood sugar in a relief position.". His potential must have changed the organizations decision though. The more I think about the trade the more it makes sense. We cant afford (giving up to many players or money) to get a stud starter. Taking a chance on someone like Morrow who is cheap and under control for four years would save us a lot of money, and could have high rewards. But as some have said, it just makes to much sense.
