In search of a ruckman and key forward target, Geelong picked up Ottens in a trade for the 2005 season. After debuting in Round 1, and becoming the one thousandth player to play a game for Geelong, he again struggled to have a major impact in the first year at his new club. He was the subject of an infamous post-match press conference by Mark Thompson in 2005. Here Thompson defended Ottens by saying "For some silly reason, you people want to assassinate him. It's just rubbish. You people, all of you, ALL OF YOU, leave him alone!" Some see it as a defining moment for Brad.
