In hindsight, the right move would have been to trade Youkilis. Look at that season, .973 OPS. He ended the season hurt, but selling high on him would have been huge. You'd get gold glove defense at the corners, and a big haul for Youk.
But then again, you'd miss out on Swihart and to a lessor extent Jackie Bradley without those Beltre draft picks. We won't really know how good a 2010 trade was for another 5 years haha.
