I would be shocked if we signed Hudson to be a one position backup player.
You start him at third as a kind of trial, and bring Morel back after DL stint if need be. If Hudson plays well, you just demote Morel after the DL stint. If Hudson plays well and Beckham really regresses, you could give Morel some more AB's and platoon Beckham, sending down Lillibridge or Escobar.
