Speaking on 6PR Breakfast, Essendon Assistant coach Mark Harvey says players throughout the history of the game have always been booed.

Harvey hopes the pressures of the game and the public and media hype doesn’t result in Adam Goodes retiring.

Fremantle’s Ryan Crowley has returned to training and Harvey says there’s plenty of positives for the Dockers to retain the tagger beyond next year.

Mark Harvey can be heard on Wednesdays before 8am on 6PR Breakfast.
