To me, it's about his health, which is a major concern and might always be one. I agree that we need to add a more sure bet 1Bman, this winter, but to me 2B/3B is the biggest hole we have by position.
A big bat (RH'd or a LHB with great splits) is actually the #1 need, but if he plays 2B or 3B, we'd be fine.
If we won't sign a great bat who plays 2B or 3B, and I'm not sure Bregman & Bichette are big enough bats to work, and Suarez might offer more offense, but to me, K Marte is the best one player addition option.
Two players could be:
2B/3B: Paredez, Bregman, Bichette, Suarez, Donovan
1B: Paredes, Suarez, YDiaz, Contreras
