Nathan Brown became the third player with the same name in the AFL when he was selected by Collingwood with the 10th selection in the 2006 National AFL Draft. Tall and mobile, Brown is a former basketballer who converted to football recently, and has been earmarked for centre halfback, following some well acclaimed performances for Vic Country in the 2006 Under 18 National Championships.
Brown made his debut for Collingwood in Round One of the 2008 against Fremantle at the Melbourne Cricket Ground in front of 45,000 fans. He immediately made impressions with speed and great defensive attributes against Matthew Pavlich, who is recognised as one of the best forwards in the game, holding him to only one goal. He would follow up immediately, playing on one of the competition's best players, Jonathan Brown of the Brisbane Lions, and Matthew Richardson of Richmond in the next fortnight, holding each to two and one goal(s) respectively.
Even though Brown was yet to make his senior debut, he was selected as the Collingwood alternative delegate for the AFLPA in 2008, behind Tarkyn Lockyer and Nick Maxwell.
Brown celebrated his 50 game in the 2010 AFL Grand Final Replay.
He has a twin brother who plays for the West Coast Eagles, Mitchell Brown and an older brother named Cameron. As a child Nathan was a Carlton supporter, while his twin brother was a Collingwood supporter.
