Once again as does happen from time to time, in an effort to keep everyone safe, a rule was created that might tend to cause even more harm. If a runner wants to break up a double play, what is he supposed to do. This rule if not enforced may even encourage more runners to go into bases this way. On the other hand, if middle infielders feel protected from take out slides will they continue to be taught how to get the hell out of the way when a guy is bearing down on them. I'm not in favor of doing anything that intentionally hurts anyone but you can't have a rule for everything I'm afraid.
