All sports should progress. Basketball, hockey and football have all added rules, changed rules, adapted rules. Some for the better, some arguably for the worse, but they've all progressed. Baseball is the slowest, and most reluctant to do so, but it too has progressed, and needs to continue to do so. The fact that it's a game doesn't mean that it shouldn't make positive change. Just because something has always been done a certain way doesn't make it the best way.
