I know it probable sounds crazy to say but the way things have worked out, I don't think they make the GF if Saifiti doesn't get sent off in round 26. I think they got so much confidence from piling on that many points against the 2nd placed team with 12 men, that it's made them believe they can do anything.
I definitely don't think they win last week, if they hadn't had that experience. I think the Warriors game pushed them to a level even they may not have known they had. That win, and getting the round 27 bye after it, I think really refreshed and bolstered their belief to a point that I don't think they reach otherwise.
Having said that, it would be handy to have Saifiti for the GF. But hey what's one more game?
