I have no doubt Braun could play a competent 1st base---it's easier to field than outfield. To me, the bigger question is how this actually improves the offensive impact of the team. Moving Braun to first and putting Parra in right leaves us with essentially the same lineup we currently have. It also limits at bats for Lucroy, unless your still going to let him play first when he's not catching, which means benching Braun or Parra. I'm all for moving Braun to 1st if it means acquiring a RF that's net worth is greater than Parra's hitting+defense, but moving the parts we have currently around just so we can keep the same guys doesn't sound like a good plan. In fact, it sounds like a great way to finish about .500.
