The concept of the untouchable player is a fallacy. That goes for any player including Mike Trout. For the right price, even he could be traded.

That said, when we talk untouchable we mean a player who can’t be replaced on the roster. In terms of the Mets, there’s only three such players on the roster.

First and foremost, Jacob deGrom is untouchable. Not only has he established himself as the best pitcher in baseball, but he’s also on a very reasonable contract. There’s nothing on the free agent or trade market available where you can replace him.

The next untouchable player is Seth Lugo, and last season is exactly the reason why. In Lugo, the Mets have one of the best and most versatile relievers in baseball. He can pitch multiple innings, get a key out, and get the save.

If you’re in a jam, Lugo can also start. No, he is not nearly as dominant as a starter. However, he can be stretched to be either a dominant opener or a competent fifth starter. Looking across baseball, there really isn’t another pitcher who offers that, not even Josh Hader.

Finally, the Mets last untouchable is Jeff McNeil. He’s that mostly because his versatility allows the Mets to build the best possible roster.

McNeil is a good defender at second and left. He can hold his own at third and right. He’s a unique batter in this era in that he’s up to hit, and he puts the ball in play. In McNeil, you’re getting a modern day Ben Zobrist in the field and a slower version of Ichiro Suzuki at the plate.

In these three players, the Mets have truly unique players whose skill sets cannot easily be replicated. In fact, you can argue, their skill sets cannot be replicated. At their relative prices, it’s nearly impossible.

As for the rest of the roster, while there are extremely good players across, they just don’t rise to this level.

While you may want to argue Pete Alonso or Dominic Smith, they are both first baseman. In fact, they’re both All-Star caliber first basemen. Unfortunately, there’s just one first base, and there’s no DH.

Andres Gimenez is very promising, but this is an organization with a lot of shortstop talent. That includes Amed Rosario, who is a capable MLB starter, and Luis Guillorme, who deserves a fair shot to play everyday.

Michael Conforto and Brandon Nimmo are approaching free agency soon, and the corner outfield position is one which can typically be filled easily. On that note, McNeil can fill one of their spots if necessary.

Like Conforto, Marcus Stroman and Noah Syndergaard are pending free agents making them more movable than they otherwise would be. Also on the pitching front is Edwin Diaz. You’ve seen reason to believe in him and believe he can’t handle New York. At the end of the day, he’s a good closer, but the Mets can always obtain one of them in free agency.

So, overall, the Mets have a deep and interesting roster. However, there are many holes across the roster. Looking at this roster, short of deGrom, Lugo, or McNeil, any of these players should be on the table to address any of the deficiencies this team has.
