Please forgive me if this question has been answered before, but with regard to Quidditch, I think Rowling created a great game; however, in the books, why does a captain only choose 6 players.  What about substitutes?

Teams always have more players on the team than actually play on the field. Subs are there if someone gets hurts, gets tired, has detention, or are used to scrimmage against.

How can a player, Dean or McCormick, just jump onto the field and play with the team without ever practicing with the team.  All players need to know how others play and team strategy.

I love the series, but this drives me crazy!
