You know, upon further evaluation, Zane might jump right atop the list of very worst Survivor contestants ever.
Here was Zane's game: The blue tribe immediately soured against Russell Swan as soon as they got to the beach and he took his leadership role. Zane then made alliances with every single person on the tribe, including making a deal with Russell and Malcolm last where he revealed to them that he had already made an alliance with everyone. At the challenge (where Swan further alienated himself against the tribe), Zane bombed and later told the tribe to vote him out due to his poor performance. On top of that, he then told everyone that he thought that Swan had found the HII, meaning that Swan could then use the idol to take out anyone he wanted to if the rest of the votes were going toward him, or to take it a step further, if they would then decide to split the votes in fear of the idol, the other votes would obviously be for "vote me out" Zane.
That's about as disastrous as it gets, even for a first boot. Especially considering that he hammed it up as being a genius, game-changing strategy in his confessions.
