It's because it's completely intuitive to her. The whole "not everyone who can do something can teach it thing".
I disagree. I do think she excels in some aspects - namely finding ways to shift the target off herself...which isn't there very often to begin with. Sandra as a player has certain advantages and disadvantages based on nothing more than her physicality. Pre-merge she's always going to be a liability, while post-merge she's almost never going to be targeted. With that said, in her first game she was on an incredibly successful tribe who dominated the challenges, so she managed to sail to the merge easily. Her second game was an All-Stars season, where challenge prowess is nowhere near as important. Who is good at challenges never enters the equation [pre-merge] in returning player seasons, it's all about the relationships. So in both her seasons she has, through no skill of her own, managed to make it to the merge and become a non-threat.
Aside from that...well she said it herself in that roundtable video. "If I don't like you, I'll come after you, I don't care about the consequences." This is Sandra to a T. Despite her insistence of being able to separate her personal feelings and the game...she has played very emotional games both times. She was determined to eliminate Fairplay and Russell in her seasons and failed each time, despite the more logical approach being to take the disliked tribemates to the end. Except that's the thing...Sandra could never 'take' anyone to the end. She plays the game as a number, not in a position of power. If more likeable people than Russell or Lil had taken her to the end, she wouldn't win. Sandra has benefited heavily both times by, through no skill of her own, being taken to the end by less likeable people.
Especially in Heroes vs. Villains thanks to Russell's complete lack of awareness.
I could go on about this a lot more, but I highly doubt I'll be changing any minds here. Again, I don't think she's an awful player, I just think she's overrated.
