TAR27 isn't over yet, but if I had to try and think of a pool, here's how it would be (From TAR27 spec)
TAR27 (Early Game):
Kelly & Shevonne (CBS gave them the first ever full photo gallery of a team spot. They were the first team to get a full montage photo album since Jet/Cord on 24 so that means CBS likes them
)
Ernest & Jin (Liked by casuals)
TAR26:
Hayley & Blair (Obviously!)
Matt & Ashley (CBS made a whole segment of them on YouTube, clearly they like them.)
Mike & Rochelle (Obviously!)
TAR25:
Kym & Alli (Obvious!)
Adam & Bethany (Obvious!)
Shelley & Nici (Fans liked them)
Tim & Te Jay (They got a montage at the end)
