To be fair, no one cared about new school players so the old school players were always going to be intimidating. Not to mention, the terrible game play of Boston Rob where he always wants to watch out for every single move made by everyone else in the tribe. I think that is where Sandra beats him, she was a social player as much as she was always sitting out on challenges and doing nothing at camp.
I mean, for the new schoolers, they pretty much watched the Survivor Legends and this is why the likes of Michelle, Ben and Nick got to stay around longer because they weren't seen as the big threats. If all these guys were playing for the first time altogether in this season with their current game play, I doubt that Ben, Michelle, Nick, Denise would have gone that far. They were saved by the perception of being less of a threat than the old school ones.
