This is the order of who I think deserves to win in the order I have them. Doesn't necessarily mean they have played the best games as it is just my opinion.
Jeremy - Fought hard and was able to stay under the radar despite playing an idol on an ally and also being a tough physical competitor
Spencer - Has had to climb from multiple different times when he felt he was at the bottom. Was actually able to do something this time to help his game rather than just survive.
Tasha - Took control of her destiny though in a brash manner. Much different than her first time playing.
Wentworth - Played an idol properly and has very few enemies on the jury. Has been in the minority for most of the game yet continues to sneak without getting people pissed at her.
Keith - Playing mostly by himself so he hasn't quite learned from his first time but is STILL in a position to possibly win because of having zero enemies on the jury.
Kimmi - Literally has only played loyal but at least she shut her mouth this time unlike in Australia. Or maybe its the edit. Most castaways say a lot of nice things about her on the island so I'm betting on a 2nd or 4th place finish for her.
