Seems to me that positions on the traveling squad would open due to injury or illness. Beyond that, the positions lowest on the depth chart would always be up for grabs, so #19 could work up to #15 by outplaying four players during practices. Once there are more than four or five "extra" players, then such gets more difficult, yes. A scout team, though, helps improve the competitive team, so they can help in practice by providing the core of the scout team. Once a couple more bodies show up, then its time to consider a B team. And once players graduate, positions will open up on the roster for the following year. A freshman who can't make the team can get much better and become a roster player as a sophomore. I don't think a roster limit will prove that limiting.

Well, I'll suggest going back and reading my post again. Nothing in it would lead to the scenario you suggest. Those players would play. They'd be at practice, developing skills. They'd be at any tourney that didn't have roster limits. They'd be filling in when roster players got ill or injured. They'd compete for the last roster positions and win them. In some tournaments the team could split into A and B squads of ten or so each. And then, as in the other sports at the school, as players graduate, spots on the roster open up and yet more players show up to compete for the last spots. Indeed, ultimate is akin to football in that all players interested would be able to practice with the team, instead of just those on the travelling roster. I think a roster limit would be a good thing for the Championship Series. That limit does _not_ mean that players must be turned away or won't be able to participate.
