Jedi Mind Tricks

There's a fine line between cheating and using your head. When A-Rod shouted "Mine!" on that pop-up, people were angry presumably because he was using mind games rather than baseball strategy to influence a baseball game; had he performed a normal takeout slide into second to break up a double play, no one would have noticed. Of course, no one objects when you call a time-out to ice the kicker, either. 

While I don't necessarily disagree, and tend to get outraged/not care right along with everybody else, it is nevertheless true that I can't find any consistent standard that I/we are applying. Which means that I can't decide whether this is a questionable idea, or simply an impressive one. It also leads to even more questions, such as: has it ever occurred to anyone that the Cleveland Browns may have an advantage when running play-action fakes?
