Hint: Easy touchdown:
When on offense go to special teams and select the punt option. When on the field, press Square for audible, then press Triangle. Wait for a couple of seconds. When you throw, the receivers should be wide open.

Hint: Touchdown dances:
Press Triangle after the play ends to make the quarterback or receiver that made the play do a touchdown dance.

Get a touchdown with the Green Bay Packers, then press Triangle to celebrate. The player will jump on the side of the spectator wall and celebrate with the crowd.
