We would be a horrible team with those guys. Will you give this a rest already? And Escobar was traded due to racial slurs in his eye paint, and ownership didn't exactly want that image. And that Pirates team went through 20 years of futility.. and we cannot afford ANY 100 loss seasons, especially being a big market team.
TDA would've frequented the DL.. he still isn't staying healthy with the Mets. And BTW, we're better off with Russell Martin catching. Yan Gomes can't take a walk to save his life this season (.218/.234/.327, 44K/3BB), and that deal the Indians gave him is going to end up being an albatross on the Indians franchise in coming years when the big money comes in (it's heavily backloaded). Plus, he's been hurt.
As for the starters, outside of Syndergaard, none of those guys would survive in the AL East.
Nicolino's numbers in AAA are awful(1.406 WHIP) plus a 4.62 FIP in the majors, which likely explains why he hasn't gotten a chance in Miami. Henderson Alvarez has been awful and hurt this season. DeSclafani has been mediocre at best, and needs a trade out of Cincy (his road numbers are much better). He cannot pitch in a small ballpark.. he needs to be in a market like San Diego, Pittsburgh or somewhere like that. Only Syndergaard is a real regret for AA.. of course, whether Noah lasts in NY will depend on ownership not making a stupid move, such as trading him for a big bat (which I can see happening, as they are under orders to make the playoffs or risk Terry Collins and Sandy Alderson losing their jobs at season's end. The Mets desperately need offense, and Syndergaard's their best trade piece.)
