Jobe Watson
Australian Rules Footballer
Australian rules footballer won the 2012 Brownlow medal as the AFL's best player - and then endangered it by testing positive for a banned substance.
Selected as the 40th pick by Essendon, he started out struggling, but improved every year, and in 2012 was voted to the 2012 All-Australian team.
An official report in 2013 revealed that he and others on his team, the Essendon Bombers, were taking performance-enhancing supplements.
His father Tim Watson also played for Essendon.
He and James Hird both starred for the Essendon Bombers.
