Ideally, both sides would pick up the mutual option, but with the way Gio is pitching, it's unlikely that he would do so. Hopefully, the two sides can work out an extension before Gio hits free agency. I don't think Gio is out for the most money, and I think he'd like to stay in Boston. Make a fair and respectable offer, and I think Gio would accept. Malcolm's post suggesting 4/$85M sounds reasonable, though my preference would be a contract for 3 years.
