Easy. Pitching is the vast majority of what produces those 27 outs, and the difference between the best fielder and the worst fielder at a given position is rarely anywhere nearly as big as the difference between the best hitter and even an average hitter--especially in the outfield. Dunn is a huge offensive producer and a liability in the field at possibly the least important defensive position. It's not a matter of having it "both ways." When a hitter is at the plate, the only person who can make an out is himself. That is not the case in the field. Outs will be made via strikeout, in the infield, or in other parts of the outfield that he has no effect on whatsoever, but he has an effect every time he comes to the plate. The situations are not parallel, and that's why not making outs at the plate is more important than making outs in the field. it absolutely is a matter of having it both ways. the concept is that outs are precious. avoid them on offense, get them on defense. but you want to say x outs are really important, y outs are not so important. it's all about winning ballgames. both are incredibly important. let's do the math. in about a year's worth of batting, 600 plate appearances, Dunn will avoid making an out approximately 230 times, Mench about 205. in a year's worth of chances to get an out in the field, Dunn will make about 25 fewer catches than a guy like Mench. the difference in outs avoided while at bat and outs given away in the field is equal. now you want to sit here and say that Dunn's 25 outs avoided is hugely important, but the 25 outs he gives back are not important. bs. in this case, the difference between a bad defender and an average defender is just as many outs as the difference between a very good hitter and an average hitter. the thesis in bold above just doesn't carry much weight when actually looking at the situation in terms of outs. as I've heard many times, a pitcher has no control on what happens after he throws the ball. it is up to the fielders to make a play if there is contact. while the leftfielder doesn't ever have an impact on all 27 putouts, he has an effect on every ball in the range of play of the leftfielder. in the case of Dunn, it's fair to say that he gives back a dozen singles and a dozen doubles a year in offense with his poor defense when compared to a player like Kevin Mench. that has an impact on winning ballgames, and when comparing him to other leftfielders, I think it is fair to subtract those two dozen hits from his offensive stats. if he's responsible for his walks and his HRs, he's also responsible for the outs he doesn't get on defense. as I already said, he's still a plus player. furthermore, I would generally prefer the offense over the defense. but pretending like his ineptitude in the field makes no / little difference on winning is absurd. his poor fielding significantly impacts his teams ability to win ballgames, and it significantly impacts his value as a baseball player.
