In 2007 Ottens was in near career best form. He played a majority of the season as Geelong's main ruckman rather than as a forward where he had played mostly since joining the club. During the Cats' five-point preliminary final win against Collingwood Ottens was voted best-on-ground after giving a game-winning performance in the ruck. The following week he capped off a stellar season, among the best players in his side's record breaking grand final victory over Port Adelaide. He noted that it was the highlight of his career.
