I really think she would win. Listen for a second. Who would have thought Tyson was going to win after his blunder in HvV? I think Corinne is in the exact same boat. Similarly to Tyson, the first time she played in Gabon she wasn't there to win. She basically just wanted to be a massive ruthless bitch and wanted to make good TV, and she she still made it to Day 33 and played a good game. Then in Caramoan she basically did what Tyson did in HvV and tried to take control of the game and made one massive mistake. Tyson totally flopped when he voted for Parvati instead of Russell, and Corinne flopped by ruining her entire plan by telling Dawn about flipping sides.
If Corrine went to play for a third time, I think she would take it way more seriously like Tyson did and I'm pretty confident she would win. She is capable of building a strong alliance and keeping their trust. She's also very self aware just like Tyson is (despite putting up this persona) and despite being such bitch, a lot of people tend to like her and trust her.
True. But Tyson and Corinne are both very charismatic. Getting along with people comes natural to them. I see them doing well in almost any cast (Corinne did fine in Caramoan despite that cast was full of lunatics and terrible players). Even in Gabon and Tocantins respectively, both Corinne and Tyson were very well liked. Their only downfalls are themselves. They both have all the 3 skills to win Survivor and it's only a matter of them applying it. Tyson actually applied those skills in BvW and he won. Corinne will be out to win in her third time, and she will have learned from her two other games.
Corrine is actually a pretty good player. In Caramoan, her and Dawn were best friends, so she thought dawn would come with her. She never watched South Pacific so she didn't know how Dawn had been in that position before. Dawn has also stated that she wouldn't have turned on Corrine had she known the jury wasn't starting. She knew Corrine would vote for her in the end, so that's why she wanted to send Corrine to the jury.
Tyson still could've gone pre-merge given a different cast in Blood vs Water, but he was given that cast, so he won.
