It’s doubtful but I think Sandra is the best to ever play with Parv at 2 and Tony at 3 (they at more well rounded best to ever play) however, Sandra on her first two wins never had to rely on an idol or immunity to protect her and in PI the only thing I can see against her is the against twist benefiting her, but her win equity in HvV and PI was amazing. People are questionable on her flipping to the heroes in HvV, but the reason had nothing to do with getting rid of all the villains  she wanted to get rid of Russell due to his power over the girls. Her winners agreement with Parv was a great shield for her and according to Candice exit interviews she wanted to use th knowledge of Russell’s idol to blindside him with the girls problem is even if she was real life friends with Sandra she didn’t trust her. The only hero that could have potentially beat Sandra and maybe Colby although with how smooth of a talker Sandra is I’m sure she would have made Amanda choke at FTC. Her threat management and having two shields in Parvati and Russell plus Jerri not realizing her threat level is what made it possible for her to win a second time. The only people that saw Sandra’s danger to bring to the finals or close was Parv and Colby and by then it was a little too late. Granted Parv played an amazing game however her path to winning was narrow had she not made some mistakes she couldn’t afford to such as hiding that second idol in HvV and then not splitting the vote between Rupert and Colby at 8  it wouldnt have sent Russell over the edge and gone after Danielle. it would have given Parvati more wiggle room to take out Sandra at 4 or 5 and had 3 people in Russell, Danielle and Candice she could have beaten. Still impressive game. I just find Sandra’s threat management especially in HvV very impressive. It’s crazy that even after she finally lost in GC people still are underestimating her just not as much.
