Until the player market finalises then I think us, Raiders, Tigers, Knights and Cowboys are all as much of a chance to make the top 8 as Bronco's, Warriors and Dragons to be honest. I also think that if the Bunnies were to lose Sam Burgess for more than 5-6 games to injury, they will struggle and may fall out of the 8. They will be without Crichton and Sutton who along with Sam were mainstays in their pack for most of the year and I don't see who they have replaced them with that will have the same work rate.
EDIT: I will also reserve judgement until the draw is released. As we have seen, it can have a big bearing on how a team goes.
