The Process is Working, Let It Work

Believe me Mets fans, I understand the frustration and the impatience, unfortunately, you can't just will a team to be better and you can't just buy free agents to make it so.
Every time the Mets have tried this (Jason Bay, Curtis Granderson, etc), it has been a disaster. And now, with more and more teams locking up their best players before they reach free agency, there are fewer good players even reaching this point. There are no Carlos Beltrans out there.

Note: This is also a big reason the Yankees missed the playoffs two years running. You just can't buy a playoff team on the open market anymore. Teams hold on to their good young players so only older, damaged veterans make it to free agency.
What the Mets have to do is accumulate good, young players and hold on to them. The Mets are well on their to building what could be an outstanding starting rotation with Harvey, deGrom and Wheeler already in the majors and others on the way. The bullpen is also stocked with great arms like Mejia and Familia and Rafael Montero.
And I am very excited about Akeel Morris who in the last two years at A-ball has struck out 149 batters in 102 innings (13k/9) and 0.79 ERA.
I also like what the Mets have up the middle with Largares (who has the potential to be a legendary defensive player) and D'Arnaud who seems to have come around. Duda, Murphy and Wright could also be positive contributors. And though I think Granderson stinks, we have him for 3 more years like it or not.
What I would like to see the Mets do is sign a left fielder to a 1-year contract and give Wilmer Flores or Dilson Herrera a chance to be an everyday shortstop.
I think the Mets can follow the Royals blueprint of a long, slow rebuilding process that bears fruit when hard-throwing young pitchers combine with speedy defensive players plus a few guys who can hit. That style of team would do well and at CitiField and be poised to do well in the playoffs when runs become harder to come by.
