The Saints could actually struggle a little, I read that they were learning the run and carry game, so they could go backwards a little bit. The Bulldogs have a lot of guys coming back from injury, so they could also struggle.
I think the Cats could get back in, depending on whether last year was just a 'bad year' or whether they have lost respect for the coach. If it's the latter, they could finish bottom.
I think the Dees will be ok, I expect Sylvia to finally come on, and McLean to continue his rise.
