Firstly I think that I need to re-phrase what I said. I think that as a 'super captain', he is a myth, but he is definitely a good captain. I sounded way too harsh.
I agree with you, a lot of it is put on his shoulders, and I do definitely agree that leadership also encompasses your actions. His performances in Istanbul and the 06 FA Cup Final particularly reflect that. But I think that a lot more of the time, when shit gets a bit tough, his head will drop a little. Last season against Crystal Palace, he should have steadied the ship for the last 10 minutes, but he just let the team completely collapse and un-do all the good work.
We definitely miss Carragher for his leadership and his experience. I sometimes ponder whether he would have actually been a better captain than Gerrard. If we had him last season, we would have won the league, I have no doubt about it. I think he'd be useful as a defensive coach.
