Note: This is just my opinion. What I classify as a best move is a move that pushed someone further in the game, whether it was flashy or not. This doesn't mean that these players are the greatest ever, though some are, but that the moves they made changed the game for them or for their allies in a major way. This is in preparation for All Stars. Also THERE WILL BE SPOILERS
Constance had control of the game. He was one of the people behind the Birks ( birks4444) blindside which was a huge move in this season where not much happened. Rob and Julian understood Constance had Grace ( pinkiepie512) Madi ( maddog16) and Gunther ( firewolf) wrapper around his finger, which he did. Rob and Julian needed to take Constance out. They were able to grab the votes to take Constance out which ended up being one of the biggest blindsides and took out one of the biggest players in YouTube Survivor history.
