A heavy deluge during the fourth quarter of the game at Etihad Stadium forced players to contend with unexpected wet weather footy.
"It is laughable," Brad said, having taken his concerns straight to the AFL's match manager on the interchange bench in the minutes after the siren. "I don't think everyone brought their ponchos."
He said the League official told him he'd checked the radar and there was no rain forecast.
"He won't be getting a job reading the news (as a) meteorologist" Brad joked.
"I just don't understand why we don't close the roof.
"There's a policy that when the sun's shining the roof's open.
"No one likes it; the fans don't like it, the broadcasters hate it, the players hate it, close it, it's not that hard."
The Kangaroos coach said it had zero impact on the result.
"I wasn't frustrated because we lost," he insisted.
Chris backed his brother: "The roof should be closed all the time."
The Cats coach reaffirmed it's not just rain that's a problem, saying "when the sun's shining, the players can't see."
The AFL said that as is it stands, it has no plans to review its roof policy.
"It is the AFL's decision whether the roof is open or closed," spokesman Patrick Keane said.
He said the decision to keep the roof open was based on the weather forecast, which had no indication of rain on Sunday morning.
But under Etihad Stadium's regulations, once the decision's made, it's made for the duration of the game.
"The roof can't be moved once people are in the ground for safety reason," Keane said.
The roof is shut for night games in the depths of winter, even if no rain is predicted, because of dew.
