Charlie Cameron is the key for Brisbane. Without Grimes, they will go with Dan Rioli IMO. Not many options outside of that so if CC gets on top we are in trouble.
It'll be Dan's biggest test to date in a final in his revived role as a HBF.
Cameron usually struggles against the bigger body defenders, even if they lack the straight line pace. Has struggle against Grimes and Hibberd in recent times. I think he'd enjoy the match up against Rioli compared to say a Vlaustin or someone of that ilk.
Unlike a lot of the team, he tends to lift in finals (16 goals from 6 finals while at Brisbane), so he'll be a key.
