Deme Tryshyn was Grav-ball's highest scorer in history. In 22 BBY, he signed the most lucrative product endorsement deal in sports history, with Ardees Beverage Company for 3.1 billion credits over three standard years. Tryshyn also signed deals with Keenigh Footwear, Herzfall Communications, and Telgorn Power Cells.
At the time, Tryshyn's agent denied any connection to his summons by the Republic Tax Collection Agency. Tryshyn had no scores in the first three matches of that season.
