Along with casting three strong male teams, honestly none of the female teams were very strong. They've actually done a lot better than I was expecting even.
As much as I can't stand her, casting somebody like Christmas with another woman would've probably been a pretty strong female team. Or even Alex from that season, or Kaycee.
With the exception of Natalie none of the women they cast from Big Brother female/female teams were in that great of shape. And even than, Natalie wasn't exactly known for being a great competitor either.
