Currently you need to go into a team in order to then see its players. With 3 teams, I have a good number of players on multiple teams. To edit a player, I need to go into each team they are on to make the same changes multiple times.
With a Players page, you would be able to view/edit player details from one place and have it carry through to the teams they are on. I envision being able to edit their name (sometimes they don't include their last name), jersey number, positions, and general notes.
