 He was also the leading possession winner in the AFL, received the most Brownlow votes for the year for Port Adelaide, and won their best and fairest, the John Cahill Medal, ahead of brother Chad.In 2010, Cornes took out his third John Cahill Medal and confirmed his reputation as the club's most consistent player through a new attacking role that went beyond his previous role of merely tagging the opposition's best players.His 36-possession, 2-goal game against the Western Bulldogs in Round 16 of that year was a highlight, in addition to a 38-possession effort against West Coast late in the year.
