On the current Dodgers roster, one of the biggest questions heading into 2016 is just what to expect from Hyun-jin Ryu, who missed all of 2015 and is recovering from shoulder surgery. My stock answer for people asking when Ryu might rejoin the Dodgers rotation has been May, and I see no reason to change that now.
By all accounts, Ryu has attacked the rehabilitation process since his arthroscopic surgery on May 21 to repair a torn labrum he reportedly pitched through for two years. I suppose a large part of my stock answer of a May 2016 return is to temper expectations; after all, it's much better to mentally plan for Ryu in May, then have him ready in April, than it is to count on the left-hander for April only to be disappointed if he isn't ready by opening day.
