That production wanted not just a female, but a black female to win this season. If you look back over the past 5 winners, 4 of them had been huge fans of the shows, which is what both Da'vonne and Zakiyah are. Also this is the first time they cast 2 black females in the same season, which doubles the odds of a black female winning. Also when they spoke with Zakiyah pre-season they probably saw a female who was likable and a student of the game. Also with 4 vets 2 siblings then she wouldn't seem like a huge threat or power player which is what I think production wanted out of Zakiyah. Then if you look at the Da'vonne she has all the tools to be a great strategic players, not saying she always uses them right. Then she be talking a lot about early days and probably pre-season about making Danielle Reyes, arguably one of the greatest big brother players easily top 10 if not top 5 female players, proud. Also she has a huge personality which I think production believe equals a good social game which is not always true.
They put in dumb guys (mostly) and floaters guys, however one of the floater guys won..
This season they put in strong females as well..
Yes they really want a black winner/Female winner really bad.
