Looking at the Mets roster right now, the team’s position player depth is defined by the presence of three players: Robinson Canó, JD Davis, and Dominic Smith. As currently constructed, the DH spot figures to be a rotation of those three players based on matchups and whomever Buck Showalter deems the “hot hand” any given day, with the other two usually on the bench.
There are certainly worse hitters you can rotate through the DH spot, and it’s not unreasonable to still expect any of those three to be difference-making offensive players for the Mets this year.
