Shambo has dodged a full clip this series (1st episode, the two men getting injured resulting in no tribal council meetings, the merging of tribes just in the nick of time; everyone temporarily forgot about Shambo playing Chicken Whisperer; riding Russell's votes against her enemies, etc.) Otherwise, she's clueless.
Natalie would easily win final against Russell because most of her former tribe is sitting on the jury, as of now. Some of his tribe members will be joining soon, but Russell will have to be part of voting them out- and that won't be pretty- so he stands to lose some of those potential votes, too.
He's made this series watchable and enjoyable.
