"I do think there’s a certain purity to the idea that everybody plays by the same rules. The significance of that purity goes up when you have interleague play every day... Particularly given the difference between leagues, in interleague play, pitchers who don’t hit on a regular basis probably are more likely to have a problem than pitchers who do."
Terrible! I hate interleague play too, but if they need one rule, get rid of the DH for both leagues.
