On each weekday of the 2011 Toyota AFL Finals Series, Leigh Matthews will count down his 20 Moments of Greatness from the finals. Today: moment No. 2 when Leo Barry threw himself at an enormous pack in a marking attempt in the dying seconds of the 2005 Grand Final.

It was 32 minutes into the final quarter of the 2005 Grand Final, with the Sydney Swans leading West Coast by four points, when Dean Cox marked on the members' wing.

Cox booted long towards the pocket at the city end.

A huge pack, consisting of about 10 players all desperate to achieve for their team, lunged towards the spinning ball.

All but one were lunging forward. The exception was Leo Barry, who stepped in from the boundary-line side and threw himself at great danger across the front of the pack.

Barry's sally stalled on reaching the pack and his ride pushed him up. His arms stretched up to grip the ball, whereupon the enormous pack fell down in a flurry of arms and legs.

Barry's mark would have been brave and brilliant in any circumstances, but its execution in the dying moments of a Grand Final lends an air of greatness.

Barry was stepping slowly back behind his mark when the siren blew to signal a famous Swans victory premiership, the first for the club in 72 years.

Teammates descended on the Swans defender. There were more in the crush of joyful Swans players than there were in the pack that had formed just seconds earlier.
