In 2007, Cornes was a key midfielder and has a largely impressive season. Cornes finished the 2007 season with 643 disposals, and led the competition in kicks, and went into the Brownlow medal count as one of the favourites. The great form of Cornes in midfield was crucial to the side making the AFL Grand Final, which was a huge surprise to most, including Cornes. Despite not expecting to have a good season, when they did make the Grand Final the belief appeared to be strong but they were unable to win their second flag, going down to Geelong by a record 119 points
