Sydney could very well drop off. They have quite a few veterans who will lose speed and struggle with injuries.
Beyond that, look what happened to the Hawks in 2008. They had heaps of young, blossoming players like Franklin, Roughead, Birchall, Rioli, Lewis, Young, Ellis, Gilham etc who were only ever meant to improve, there was no way they could go backwards but many of them did in 2009. The same thing could happen with Kennedy, Jack, Hannebery, Jetta, Reid, Parker, Smith, etc. You never know.
Having said that, I don't think that will happen.
