Agreed, it's not a great way to judge a team, but it's also not completely meaningless, just really insignificant. I couldn't find recent numbers, but studies in the 90s showed that runners on 1st usually score between 25-30% of the time (depending on the year in question). I'm taking the 25% number because it's easier for my purposes...but if you hit into 1 DP a game you are essentially preventing your team from scoring 40 runs over the course of a season. That sounds like quite a few runs to me, of course it matters a lot more if you only scored 600 times in the season to begin with than if you scored 800, and it matters more if you are in a very tight playoff race where 1 win matters. Of course, every other team is also hitting into double plays, even in a bad year you probably won't hit into 40-60 more than any opponent, meaning the actual "cost" in runs compared to the best in the league is probably no more than 10-15 runs over the course of the season. That really doesn't seem like it's a number that would have much of an impact on too many teams, especially when you consider a lot of those double plays occur in games you lose by more than a couple runs anyway. HOWEVER, if you're the Minnesota Twins and you seem to end up playing in game 163 more often than most mortal teams, that 1 game you lost because you hit into so many dang double plays could matter. But, it's real slim odds of that being the case.
