Adelaide's Isaac Cumming has urged Crows fans to be a "bit more respectful" after Collingwood defender Isaac Quaynor was subjected to booing from sections of the crowd in their round 20 clash.
Quaynor was the target of a homophobic slur from Adelaide's Izak Rankine in a game last August that resulted in a four-game ban for the star Crow, putting him out of the finals.
