Roster
"The secret is to have eight great players and four others who will cheer like crazy."
On the Roster page, you'll find a very detailed description of your players and their skills. You might find it useful to sort your players using the Sort By: drop-down menu near the top of the page.
When you link to a different team's roster from their home page, you'll see only each players weekly salary, age, height, and best position. If you want more information, you'll have to analyze the player box score history, which can be reached by clicking on the name of the player. If you click on your own player, you'll have access to some additional features; you can set his jersey number (if you are a supporter), put him on the transfer market, or fire him.
