Don't get me wrong, I like Creagh as a player and, from what I have seen in interviews etc, he seems like a nice guy. Longevity should count for something, but should definitely be second to leadership quality (afterall, you don't want to be accused of the 'boys club' mentality). Ben is doing an OK job and does have leadership qualities, but I think we could also benefit from a different leadership style at the moment.
On the field, although he does lead by example, he doesn't appear to do all that much talking. And given we have had a young team the last few years, I think a good talker and motivator on the field would make all the difference. How many times did you see the team congratulating each other or talking to each other during last season? I hardly saw that at all. I think the captain should have been promoting that sort of behavior on the field - just not sure Creagh is that type of leader though.
This year may be different with more experience being added, but we still need that constant talking, motivation and direction. Someone in the thick of things for most of the game. Will be interesting to see what difference the added experience makes to the team this year.
