"It probably makes for good theatre but we are trying to win a footy game."
Griffin revealed that Barba appeared nothing like the confident performer who led the Bulldogs to the 2012 NRL grand final when he first arrived at Red Hill.
Keen to bounce back from dramas on and off the field, Barba cut a coy figure when introduced at training.
"He was probably a bit nervous," Griffin said. "But as the months have gone on and he got to know the guys he has become more relaxed. He has been good for the team just in the way he has conducted himself and his attitude."
Barba now is a world away from the man who missed the opening rounds of 2013 through personal issues. Ankle dramas then sabotaged his season before Barba was granted a Bulldogs release to be closer to his family after his estranged wife relocated from Sydney to Brisbane.
Barba has been given every chance to reclaim his stunning 2012 form this season as Brisbane look to bounce back from 2013's 12th placing - their worst season finish.
He has been handed a roaming role in attack, running off a forward pack led by co-captain Corey Parker, who had a league-high 68 offloads last season.
The Bulldogs will also be out to exorcise last year's demons. As Barba succumbed to the pressure of being the NRL's latest pin-up boy, Canterbury started last year 1-5, sparking questions about team harmony. They were eventually knocked out in the first week of finals 22-6 by Newcastle.
The Bulldogs - who have not lost at home to the Broncos since 2008 - will battle without Krisnan Inu (broken jaw), Sam Kasiano (foot), Greg Eastwood (foot), Drury Low (broken hand) and Tim Lafai (broken hand). AAP
