DH baseball is a better, more interesting game than non-DH baseball. If baseball had evolved in a way that didn't cause pitchers as a group to be worse hitters by orders of magnitude than everybody else, that would be great, but it didn't. The argument that non-DH baseball is more strategically interesting, IMHO, misconceives what strategy means. Being forced to do something because of a systematic weakness isn't a strategy; it's a reflex. The absence of the DH causes managers to do things, but those things aren't interesting strategic decisions, they're reflexes. The argument is just odd on its own terms: "It's more interesting to force teams to play a guy who's abysmally bad." If that's so interesting, then let's make the starting 2b hit with a pool noodle. That would be downright fascinating. Tradition? Very few living fans remember life before the DH. To most fans, a version of MLB where all pitchers hit has no more relevance than the versions where fielding gloves were basically made of wood and where there were no teams in the South or West. If traditions aren't substantively good, they only matter until people get over them. Variety between leagues? This is the one argument I sort of sympathize with. Having different versions of the game to watch is fun. But if we want variety, why just this one variable? Back in the 70s, a lot of newer stadiums had astroturf. That was genuinely interesting and made for different styles of play. Unfortunately guys' knees started disintegrating, so that experiment had to end. If we really want to promote variety, we should actually promote variety in multiple creative ways, not just back into it by clinging to one difference between the leagues. Also, cross-league variety makes a lot less sense when the leagues play one another. I wish they didn't, but that train has long since left the station. DH everywhere.
