The Statistics tab can be altered to fit your individual needs.
To remove unwanted stats, just click on the Manage Stats button. From this window, you can click the Delete button next to the Stat you want to delete. Please note that once deleted, the Stat cannot be automatically added back, it will need to be recreated by adding a formula using the New Statistics button.
To create a custom stat, click on the Manage Stats> New Statistics buttons. From the New Statistics window you can create your custom stat. Once saved it will appear in your Stats and tally for your team.
