He was appointed as assistant to head coach Ivan Henjak for the 2010 NRL season, in which the Broncos failed to make the finals series for the first time since 1991. Less than three weeks from the beginning of the 2011 NRL season, Griffin became the third ever coach of the Broncos when he was unexpectedly announced to be replacing Henjak. After losing their first match, the Broncos went on to win seven matches in a row, to be sitting equal top of the ladder with the St. George Illawarra Dragons at the conclusion of Round 8. Griffin employed a policy of resting key players such as Darren Lockyer and Sam Thaiday after mid-season representative matches and Brisbane's ladder position slipped. However they returned to the top four after the 2011 State of Origin series. The Broncos finished the regular season in third place, their best finish to the regular season since their last premiership in 2006. Griffin then took them to within one match of the grand final.

Penrith Panthers
On 21 October 2015 it was announced that Griffin had accepted the head coaching position with the Penrith Panthers on a three-year deal.

On 6 of August 2018, Griffin and the Penrith Panthers club decided to part ways with immediate effect, leaving assistant coachCameron Ciraldo as caretaker coach. In the aftermath of being sacked by Penrith, Griffin and Gould proceeded to trade barbs in the media. Gould went on record as saying “We just got the feeling that everything Anthony has brought to the club over the last three years, we’ve probably seen the best of it … I think the pressure from the media and constant speculation was eating away at him … Anthony is very old school, he likes to do everything himself. I think in the modern day age the head coach has got to rely on the expertise, knowledge and assistance". Griffin later came out and said “He hasn’t coached for 20 years. He hasn’t had his head in the fire for 20 years. If there’s anyone old school in the conversation — if I’m in the conversation about being old school, he’d need to be there as well". Griffin then later spoke of Gould claiming that he was sad after a win and happy after a loss. Griffin told the media “We were officially on top of the ladder, having overcome this huge run of injuries earlier in the year, but nothing. When we lost there was always an inquiry, how had we had failed in our preparation, but there was never any inquiry when we won". “I have never seen him so happy than when Brisbane put 50 on us. And then I’ve never seen him so agitated than when we just beat Manly ".
Radio career
