I will say this; while I'm not a fan of NL baseball with the pitchers batting, all the double switches, the bottom of every line up is soft as toilet paper, etc, etc, but that said, NL managers have a much, much tougher job than AL managers. They have to decide when to pinch hit for a pitcher, how to use the bench, when to leave a pitcher in, when is the pitcher up so he can gauge who's left on the bench to pinch hit, it's a nightmare trying to keep track of it.
AL managers just plug in the DH and fall asleep in the dugout.
Two totally different games.
