Who's moving to 1B? ... Donaldson. This ain't Beltre who was still a great 3B who needed to restore some counting stats so he could make money. It's an injured guy who is past his prime but can stiill hit.
Britton, if healthy is an obvious "sure why not" choice. He is such an absurd ground ball pitcher that his floor is extremely high. If it wasn't for the Lisfranc, Herrera would be the best reliever on the market.
