There's more to being a captain than shouting and moaning at refs.
I like Dicker and even though his performances this season maybe haven't hit the heights of previous campaigns, he doesn't shy away from responsibility. He is always putting himself about, tackling and making himself available to take the ball off the back 4. He is a calming influence at times,and leads by example.
It isn't his fault we are lacking in creativity going forward. His job has always been to work with Power as enforcers, and they do it well. They need a Mulumbu/ Jones/ Stewart type player to give the ball to.
