All coach game-day use cases are buried in a three-level tab menu accessible from the "My Account" page.  None of the tabs actually look like tabs in the interface:

  - Select your own coach role in the "My Family Members" set of tabs
  - Select the "Teams" tab underneath your coach role.
  - Select the "Tournament & Schedule Apps." tab underneath the "Teams" tab.
