With Price succumbing to career-ending complications from heel surgery and Mannering leading a revival that began with a return to the finals in 2010 followed by last year's grand final run, history now looks kindly upon that decision. At the time, however, it appeared anything but a no-brainer.
There were concerns about how a depowered and disappointed Price might react, while many assumed vice-captain Micheal Luck to be the natural successor.
"I guess that was more from the outside in," Mannering said when asked to reflect on that time. "Within these walls it was never an issue. I was fine within myself - the club had taken a decision and I was proud to be taking the role. All I wanted to do was play the best I could and do as good a job as I could for the team. I've enjoyed every moment of it, good times and bad."
There has been a fair bit of both during his 50-game reign. The resurgent 2010 campaign ended in crushing disappointment when the club were eliminated in the opening round of the finals, while last year's rollercoaster ride included starting the season with three straight losses and a mid-season four-match losing streak that was capped by Cleary announcing his departure to Penrith.
"It hasn't been smooth sailing, you go through tough times. People question your ability, not just as a captain but a player. You expect that and how you bounce back is what really counts."
He hasn't altered his laid back style much but Mannering certainly seems more comfortable in the job these days. He knows he'll never be a public figurehead in the mould of Price. "I'm not going to try to be anyone I am not. I'm hoping I've improved over time. I guess starting fairly young you learn along the way. But everyone here carries their own weight. It's not like it's a burden."
As for bringing up 150 matches, Mannering says: "I'm sure in the future there will be a whole lot and you won't even remember me."
That seems unlikely.
