Very True, if the above issues were to be decided by the whole team there would be a lot of unhappy people, lots of cross arugments and well no final decision. Specially things like deciding who goes on what trip (money concerns)
discipline for studetns who break rules (school and team), these things have to be looked over by someone who is non bias, and deals with each student fairly.
.
Thats my opinnion anyways.
