She made it to the end and she did a lot. I think its wrong to say she did nothing.She didn't bully anyone and the production edited a lot of stuff.
About challenges, when someone wins a lot of challenges the others go after them, it happened with Laura last season, and many others. Besides when Boston Rob was there and they were winning most of the puzzles Sandra was always helping.
Her and Parvarti deserve another title and price just for putting with the biggest loser , bully, arrogant, egocentric,Narcissist, lazy etc etc ....Russell.
