Create logins for specific pages

What is the best way to go about this?
For example: I would like to create a site for a sports league that has 10 teams. When the sports teams go the same homepage, they are presented with a list of team names. When they select their team name,
they are redirected to a login form, for which I would have set their user name and password. Once they input the correct login, they can access a page that contains their schedule, stats, etc… Essentially, I want to create a site, with multiple logins that I can only set. Each login going to a different page on the same site. What is the best way to achieve this, or if there are other ways that I have not thought of, I would appreciate your input.
