I want to know the answer to the following question:
Why did Green make a deal to shore up the starting rotation?
All the background I'm provided with is that "Joe Carter (who was with the Triple-A Iowa Cubs at the time) and center fielder Mel Hall were sent to Cleveland for Sutcliffe and back-up catcher Ron Hassey (.333 with Cubs in 1984).". Is that enough to answer the question?
Answer: no
