Brogan was part of the 36ers team that won the 1998 NBL championship over the South East Melbourne Magic with a 2–0 clean sweep of the Grand Final series. Brogan didn't get on the court in Adelaide's 100–93 home win at the Powerhouse, and was only subbed on late in Game 2 at the National Tennis Centre with the 36ers holding an unbeatable lead. Within moments of coming on, Brogan was fouled and described his two free throws as "almost air balled" (teammate Rupert Sapwell later jokingly asked ""what differentiates that from any other game?""). However, after missing his second shot, he then hustled back on defence and took a charge from the Magic's Frank Drmic causing a turnover and giving the ball straight back to the 36ers. Adelaide won the game over the Magic (who were the minor premiers with an imposing 28–6 record) 90-62 for their second NBL title.
