post-2017 pitching isn't something i particularly worry about; we'll most likely have similarly elite defense throughout with Russell, Almora, Rizzo, Bryant, Heyward? as fixtures and a powerhouse lineup upon adding Contreras (and possibly? the NL DH) so let Jake & John walk and just sign Tanaka/Garcia/Cobb/Darvish/Chatwood/Tillman/Pineda/Eovaldi/Duffy/Lynn/Buchholz/Liriano...there are at least a dozen guys that are perfectly fine options like Lester, Lackey and Hammel currently are and the year after has Fernandez/Harvey/Keuchel/Richards/Kershaw?/Price? plus, fwiw
