Dodgers: With Bumgarner gone, what’s next for LA’s rotation?

The Dodgers had some interest in Madison Bumgarner but the former Giant is headed to Arizona. With another free agent target off the board, what’s next for LA?
Last week at the Winter Meetings, the Dodgers had interest in Madison Bumgarner. Not only did the Dodgers have talks with Bumgarner’s representatives but MLB insider Ken Rosenthal even proclaimed that the Dodgers were shifting their attention to Madison Bumgarner when Gerrit Cole agreed to a deal with the Yankees.
Now to many Dodger fans’ joy, Madison Bumgarner is off the board as he agreed to a five year $85 million dollar deal with the Arizona Diamondbacks. So now the Dodgers can cross another one of their 12 targets off the list and move on to the next one. The most obvious and familiar name that comes to mind is Hyun-Jin Ryu but there is no shortage of interest in the NL Cy Young award runner up.
Here are a few routes the Dodgers could go with their rotation now that MadBum is no longer available in free agency.
