So in Half blood prince Harry had tryouts for Quidditch. Fair enough, most of the last team had finished the school. but why the hell did he have to hold tryouts for the players he already had?
He had Ron as goalkeeper. Why should McLaggen be tried out as goalkeeper, when he already had one? In Book V it's stated that there are tryouts for goalkeeper, as Wood left, and the rest of the team should just be there to see how the new one fits in. Ron had already become a keeper in the last book and won the quidditch finales So, why have tryouts in the first place?
