I think handing out a derby medal is a great finish to the day. But I loathe the fact that it's names after a predominantly eagles figure.
How about this solution?
2 teams
2 games a year, 1 home game each
Hand out the Derby medal each time.
For an Eagles home game let them organise it, the selection panel, and let them call it whatever they like.
Likewise for a Freo home game, let us organise it and call it whatever we like.
I vote the Kickett medal and we give it to whoever hits an eagle the hardest
