I like where you're headed there, but no way Arcia enters that equation. He occasionally crushed an HR, but he was a major detriment in the field, strikes out a ton, and isn't a real heady player, either. I'd be shocked if we see him in Target Field again.
They'll never do it, but my plan would put Mauer back at catcher where he can add some value (still way overpaid), put Plouffe/Sano at 1st/3rd (or vice versa). Then, could play Hicks in RF - or Kepler if ready. Would be a great defensive OF. Twins will always let Joe do whatever he wants, despite being way overpaid.
