Rookie Brisbane Lions coach Michael Voss admitted he had made "a thousand" mistakes in his first year - but looked forward to learning from all of them in 2010.

As assistants Chris Johnson and Wayne and Craig Brittain announced their departure from the AFL club, Voss looked ahead for a rejuvenated Lions after they were bounced out of the semi-finals by the Western Bulldogs.

And almost 12 months after initially taking over the Lions coaching reins from the legendary Leigh Matthews, Voss liked what he saw.

"Sometimes you have to take a reality check and look at the group and say what have we achieved?" Voss said.

"But when you reflect back on where we stated from ... and what we have been able to achieve, you would have to say we have done a lot.

"I am proud of what the group has been able to do.

"But we have always got to raise the bar."

Voss admitted he would learn from his many mistakes in 2010.

"There are a thousand things (I would have done differently)," he said.

"You learn off what you've done well, but you learn more from perhaps the mistakes you make - and I've made a thousand of them.

"(But) I don't think a lot of people thought we could get to where we were so that was credit to the players.

"But whenever you get to that point there is a standard or expectation set.

"Hopefully the next step for us is another level - but we don't presume anything."

While his players indulged in Mad Monday drinks, Voss announced an official club review would begin on Thursday.

But already changes are being made.

Johnson told the club he would be moving back home to Victoria for personal reasons after spending two seasons with the club on the coaching staff.

He took up the role as development coach after a glittering 14 year playing career that included the Lions' three premierships.

Wayne and Craig Brittain will develop their own business.

Wayne was an assistant since 2008 while his brother Craig made a significant mark in development, recruitment and coaching the reserves side since arriving in 2000.

More staff changes are expected after Voss reviews his player list.

"You always modify, every season there are going to be some players that will be here next year, some won't be," Voss said.

"In terms of things that we need, we'd obviously like extra speed in the midfield - we'd like an extra defender.

"To get those things, you either develop it, or go get it yourself - and both are difficult."

Richmond defender Andrew Raines and ex-Lion Richard Hadley have been linked with the club, and midfielder Bradd Dalziell is reportedly tipped to move back to Perth.

"There is always talk. The football grapevine is a beautiful thing," Voss said.
