This is the summary of Big Brother 20: Bayleigh: YOU ARE NOT GETTING MY VOTE Tyler: I don’t need your vote! Julie Chen: And it all comes down to Bayleigh’s vote, and congratulations KAYCEE, you are the new winner of Big Brother!
I don't think there's any way Tyler can win against Kaycee in the end. She's made a lot less enemies this season, but has still proven to be a comp beast. If Tyler were smart, he would have taken Brett or Angela to the end. But he's already proven he's sticking to the plan he made week 3 with Kaycee despite the changing circumstances.
Everyone should take her to the end, but Kaycee always takes Tyler over Angela and I've never heard Tyler say that he wants to take Angela to end. However I do think there is a chance that he changes his mind.
Tyler started out as the strongest force in the game, but overtime it just felt predictable that his alliance was just going to dominate, and the jury decided Kaycee had a better gameplay by not pissing off Bayleigh, Rockstar, or Scottie
