Troyzan at least tried to scramble and cause some disfunction, but, yes, it was too little too late, and I never once thought he'd be able to pull it off.
There were a few problems with it - the first was RISK. it was a sort of prisoner's dilemma where he needed everyone to come on board, but they wouldn't all trust each other to come on board. and if you did flop but did not get the 5 votes, you'd have a huge target and probably be gone next. For example, if he had gotten Leif, and Christina, and Alicia, but not Tarzan, than Christina and Alicia would be hung out to dry.
The other problem was REWARD. is that he kept telling people Final 5 which was not enough of a reward and essentially what they had anyway and with a existing alliance and no risk. He needed to embellish or convince Alicia and Christina and Tarzan and Leif independently that they were Final 3 and in the final jury.
I still find Survivor entertaining but the number of people truly playing the game (guys and girls) is a little depressing. Part of the reason I loved the chaos and constant scheming of the Russell seasons. We are a long ways from that.
