His Simpson Medal winning performance in his last game, propelling Perth to a two-point victory in the 1955 grand final (Perth's first for 48 years), is legendary. At half-time, East Fremantle had a 34-point lead, but in the third quarter McIntosh led his side to get within two points at the last change. In the final quarter, kicking into the wind, Perth managed to get in front and hold East Fremantle at bay to win 11.11 (77) to 11.9 (75). McIntosh's strategy was to stay in the dead pocket and repeatedly knock the ball out-of-bounds.
He won seven best and fairest awards for his club. He is depicted in a Western Australian state guernsey in Jamie Cooper's painting The Game That Made Australia, commissioned by the AFL in 2008 to celebrate the 150th anniversary of the sport.
