They're unlikely to find a quality starting arm outside the organization for the next 2 months, unless they are willing to pay an arm and a leg (no pun intended!). Duffey had a rough 2016 season, no doubt, but I'm not sure he is a completely failed starter. Was Berrios a failed starter after last year too? Was Hughes a failed starter after 2011 or 2013? Was Ervin Santana a failed starter after 2007, 2009, or 2012? Everyone knew Duffey would have adjustments to make after 2015, and he didn't really get a break to make them after he started struggling in 2016 -- we kept throwing him out there every 5th day on a pretty dysfunctional MLB squad. He only returned to the minors for 2 starts, at the end of August and early September, and then was right back into the fire. We seem to be giving credit to the new leadership, coaches, and catchers for helping get other guys on track in 2017 after a difficult 2016. I'm not sure why we're not extending the same benefit of the doubt to Duffey -- his current success may not be solely due to his bullpen assignment.
