The DH rule for Major League Baseball is a good rule

I agree with the first two sentences of your contention. I am not sure about whether or not the DH increases the number of fans, we'd have to look at NL vs AL attendance. But that is really not my point. I am not arguing over the empirical question of whether or not the DH rule helps earn money for teams. I am asking the question that isn't empirical over whether or not the DH makes the quality of baseball better. I'll now respond to your disagreements and clarify my contentions. 1st. All players are different but they are equally fielders. The DH may be used for any fielder and it is completely arbitrary that one fielder gets to not bat. True specific players have specific roles, however, this does not mean they do not have both an offensive and defensive role. This is what it means to play baseball, that is, to play offense and defense. The specific roles on offense and defense is secondary and not essential, The football analogy does not work. The reason is that football substitutions are very different. Really any player in football can play anywhere at any time in the game. This is why players come in and out all the time, switch positions, play special teams, and even sometimes in non-professional levels play both offense and defense. Baseball on the other hand is not a game like that, the players who are in the game are simply in the game. The general rule is to play offense and defense, the exception is the DH. This is very different from football so the analogy fails. Even if it succeeded, football is a different sport with a different set of questions and therefore does not change whether or not the DH is actually good for baseball. 2nd. I somewhat agree, somewhat disagree. First off, defense correlates slightly better with winning than does offense. Still, this is overall defense and overall offense not individual players. Remember though, fielding percentage is not the only consideration when it comes to fielding. Often times we do not even notice the fielder's contributions. When a right fielder gets the ball after a single, he may hold the runner on first or hold a runner who was on first to second simply by the fact that he is known to have a good arm. Second, range matters as well in terms of preventing hits, limiting EBH, turning double plays, etc. There is more to the story however. My point is about strategy. It is not so black and white. If two players are very similar in terms of batting does fielding play any role? Is the Gold Glove meaningless? Also, there are other factors besides hitting that are important offensively. If we open up more slots for hitters, these become less important. In other words, there may not be a need to choose between a .300 hitter with 20 stolen bases and a .280 hitter with 20 homeruns because both can play. Finally my point about pinch hitting for the pitcher remains. 3rd. Defense and offense are both important. Baseball is about scoring more than you let up. Also, I am not saying that hitting is too strong in the sense that too many runs are scored. I am saying that there is too much emphasis on the offense in baseball. There should be equal emphasis for the sake of the game. A DH balances the emphasis to the offensive side because it includes an extra hitter simply for the sake of his hitting ability.
