Geelong winger Isaac Smith has become the oldest Norm Smith Medallist in VFL/AFL history, saving one of the best games of his career for the biggest stage of all.

The 33-year-old Smith beat Patrick Dangerfield to the medal on the back of a 32-disposal, three-goal game.

Isaac Smith said he was "in shock" after the game at how well his Geelong side had played

One of a number of Cats veterans that many had written off before the season as past their best, Smith took particular pleasure in proving the team's doubters wrong.

Smith won three premierships with Hawthorn last decade before joining Geelong ahead of the 2021 season.

He paid tribute to the club culture at the Cats, which he says helped foster the environment for this success.

Smith said the culture at Geelong and the "balance" afforded the players allowed them to play their best
