As I’ve stated several times in the past, I have am generally anti-DH for personal and subjective reasons, but I accept that it makes more logical sense for both leagues to have the DH. And I think it’ll happen eventually, my personal and subjective opinions notwithstanding.
To the extent people want to argue about it on objective, as opposed to subjective grounds, however, here’s a new data point for your consideration: the DH does not cause the games to go longer in any appreciable way. Carl Bialik of FiveThirtyEight looks at the data, and it’s pretty interesting.
You may now post 100 comments in which you try to disguise your personal preferences regarding the DH as objective criteria. I’ll start: it has been scientifically proven that liking the DH causes most cancers. Period.
