General managers of baseball teams are constantly making decisions that will impact the future of their clubs. Grading them on only two decisions might be a bit unfair, but it makes for an interesting exercise. As we did with the American League earlier this week, now it's the turn of every National League GM to be graded solely on their best and worst trades, with an emphasis on moves made with their current team when possible. Finally, where the GM is not the head decision-maker for baseball operations, the GM is listed in parentheses.
