The Mets could best stabilize their rotation for this season by signing Lance Lynn, Alex Cobb, or Jake Arrieta to a multiyear deal. However, having Lynn, Cobb or Arietta in the mix can help in other ways, as well... Matt Harvey will be a free agent after this season and almost certainly will leave for a new team. The way it stands, J.A. Happ, Cole Hamels, Gio Gonzalez, and Dallas Keuchel are the other top free-agent starting pitchers set to be available next winter. It's a list that leaves a lot to be desired... In a perfect world, Steven Matz, Zack Wheeler, Seth Lugo, and Robert Gsellman all thrive in 2018 and the Mets never need to replace Harvey. The odds of that happening are low, though... In signing Lynn, Cobb, or Arrieta to a longer-term deal now, though not the greatest pitchers on earth, it would at least give the Mets a durable, experienced, veteran starting pitcher under contract and mean they do not have to go through a weak free agent market in nine months. In case you're curious, Jacob deGrom is a free agent after the 2020 season. Noah Syndergaard can be a free after 2021.
