The Mets will be pitched by teams looking to acquire Jacob deGrom and Noah Syndergaard. However, despite all the buzz, I expect both pitchers will continue being Mets at least through the next two seasons.
Frankly, the only way I see either of these two pitchers being traded is if a new GM and front office takes the wheel. Otherwise, it's ride or die with deGrom and Syndergaard for Sandy Alderson.
Similarly, while there will be interest in (and it's worth listening to offers for) Seth Lugo and Robert Gsellman, my hunch is Alderson would prefer to keep them as well -- especially given the delicate state of his rotation.
