Isn't it really about dotting a guy who had done nothing but play well? I don't think I have seen anything about Harper doing anything wrong, questionable, or disrespectful. He's just good.
He bragged about dotting a guy that he was scared of? Just because he felt like it?
If so, yeah, there is no room in baseball for that. He should have a serious suspension. Start him at one month. He'll get the union rep to negotiate it down to 3 weeks.
