SYDNEY Swans coach Paul Roos said Barry Hall’s latest transgressions had come as a surprise after the forward had enjoyed a settled year both on and off the field.

Hall underwent counselling with psychologist Grant Brecht during a club-imposed suspension last year after receiving a one-match ban for attempting to strike Collingwood defender Shane Wakelin.

It followed a seven-match ban for his strike on West Coast’s Brent Staker earlier in the year.

Roos said he had thought Hall’s mental troubles were behind him.

“Where we’re more confused this year is that everything seems to be going really well,” he said.

“Everyone comments about how well he’s going off the field, and anyone that saw him before the game on Saturday felt that he was in really good spirits.

“Nothing I’ve heard this year has led me to believe that things like this would happen or the Hawthorn game would happen.”

Roos said he was yet to speak with the playing group as Monday was a player-free day at the club.

But he said Hall’s actions “clearly” set a bad example for the Swans’ young players as the club embarks on a period of rejuvenation.

“As a footy club, we want to be seen as a disciplined football club. We’ve built up a really good culture here as a football club,” Roos said.

“As you move into the next phase, you try to provide some really good guidance for those younger players coming into the forward line.

“How much impact what he did on the weekend had, I’m not really sure because I didn’t see it until after the game.

“But every incident impacts on the team, either negatively or positively and it also impacts on those younger guys coming into the footy club.”
