Actually Brogan wasnt the first NBL Championship player to play VFL/AFL, although he is the only one to pick up a premiership in VFL/AFL as well. That honour went to the late Mike Parsons.
Michael "Mike" Parsons (3 October 1960 - 24 April 2009) was a former Australian rules footballer who played for the Sydney Swans in the VFL/AFL and North Adelaide in the South Australian National Football League (SANFL).
Parsons was initially a National Basketball League player during the early 1980s, when he spent time with both Launceston Casino City and the West Adelaide Bearcats. Most notably, he played at Launceston in the 1981 NBL Season, where they were League Champions.
Parsons, a ruckman, is best remembered in football circles for his Jack Oatey Medal winning performance in North Adelaide's 1987 SANFL Grand Final win. He was then recruited to Sydney with the tenth pick in the 1987 VFL Draft but struggled to make an impact in his three years, although he gathered three Brownlow Medal votes for his 23 disposal effort in a match against the West Coast Eagles midway through his first season. Parsons returned to North Adelaide in 1991 and finished the year as a member of another premiership team.
In 2008, Parsons suffered a stroke and was revealed to be suffering from a brain tumour. He died in hospital on 24 April 2009
