Chris played the hand he was dealt near perfectly (after messing up initially before getting voted to EoE). He schmoozed the jury endlessly, getting potential votes and information. The other players at EoE were idiots to share so much information, and he used it when he got back into the game. He played Lauren (who was a complete moron to use her idol to save him) and then made his "big" move to take out Rick Devins (which was the ONLY way he could have won the game. If Devins had won the firemaking challenge, he would have won the game. If Gavin (or Julie) had beaten Devins at firemaking, HE (or she) would have won the game.
I hate the whole EoE twist, and the firemaking at final four, but that was the game they were playing.
