most of the reasonings behind your points are based on the experience of the players.
ie; college students won't be any new player, they understand the rules, and have to act well to keep their tag they worked for. however bobcats consist of new players, who don't mind causing trouble ( especially the gangrpers who just want to bait their b-tec adult role )
plus, i enjoy the fact that spartans are 'better' at things, obviously since they are older, and more experienced in the things they do. i think spartans should actually have more respect from bobcats icly, since that's very traditional in japan, just keep the rivalry between the sports teams..
