Re: Give the gold to Silva
Again Lillipop, consider the conditions in which he's had success. Minnesota has been among the leaders in defensive efficiency during his tenure. I don't disagree with your basic premise, but as M2 rightly pointed out, he's league average in a best case scenario. Given the Reds horrible defense, committing significant money to a mediocre at best upside, and disastrous downside isn't too smart. There are legitimate reasons to believe he would not likely match his Twins' success as a Red.
It's one thing to commit to a guy like that for a year or two, or at minimal financial risk (think Matt Belisle). However, with limited resources, you need something that more closely resembles a sure thing in this environment.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
