To have a chance at 81 wins in 2012, the Twins have to improve their run differential by 200 runs. (They scored 619 last year and allowed 804) I'm interested in your opinions on how many runs you think the various player changes and returns to health can account for. I'll start by saying that I think having Ben Revere in left field instead of Delmon Young accounts for 10 fewer runs allowed simply based on the number of additional fly balls that Revere will get to. I think it will be more than that but am accounting for some of the exta bases Young's arm may have limited that Revere's will not. 190 runs to go...
