Here's a simple but useful way to look at it - call it Bill James in the 5th grade. First of all, nobody gets more frustrated than me watching Florimon bat. Its not even the lack of hits but the lack of productive outs that really drive me nuts, however..... The difference between Florimon at .210 and Nunez at .260 is 25 hits over 500 ABs (call it one season). Assume the majority of those "difference" hits are singles, which they likely are given the light hitting nature of the position. Also assume that many of those 25 are going to be hits that occur when there are no run scoring opportunities. Now examine from a fielding perspective. Given the nature of the plays at shortstop, an error or an extra ball that Florimon would track down due to his greater range, would be roughly the equivalent of a single, very similar to the extra hits examined above. Like above, some would happen during run scoring opportunities, most would not. So, we could quantify the difference as: would the total of Florimon's fewer errors plus the extra balls he would get to be greater than 25? I am guessing the answer to this is clearly yes, especially if you consider double plays he starts on balls Nunez wouldn't get to. Clearly, both players are flawed and what we really need is a guy that can field and hit adequately but in the current environment, we are probably better off with the better defense. I'm sure somebody that is better with sabrmetrics could use OPS to do a similar, better examination but I think, in a crude way, this illustrates that unless one hitter is going to provide much more in the way of extra base hits, the difference isn't as large as people tend to assume.
