Wow...thankfully I don't see that happening at my son's school or in our area. A school simply wouldn't be able to field a strong team with such a backwards approach. (I actually thought you were being sarcastic at first because that is so far from my experience....)
My son's coach will play whoever can get him a win. If anything, he might be too quick to move from pitcher to pitcher looking for something that will work. No politics.
