However, Adelaide had both Perth Wildcats 1995 championship player Martin Cattalini as well as club legend Mark Davis in front of him for the Power forward position.

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?").

With Cattalini and Davis still with the 36ers for the 1998–99 NBL season, plus the addition of centre/forward David Stiff to the squad, Brogan felt his chances of breaking into the Adelaide starting line up were limited and he moved to play for the struggling Newcastle Falcons after the 36ers 1998 championship win.

He spent the 2000 season playing for South Adelaide in the SANFL, attempting to transition his skills from basketball to football and a year later made his AFL debut in 2001.
