I honestly think it should go to Ohtani. I've interpreted MVP awards more of a "best player" thing even though it is literally called "most valuable player." Ohtani, because his team sucks, does not have a chance to get his team over the top and into the playoffs or into a division title. It never has made sense to me to hold that against a player. He cannot control that.
Ohtani is having a season whose only precedent is a past season by him. Don't you, almost by definition, have to give the award to him?
