This would have been the point at which the outsiders could have united and made their move. If Rick and Edna would have recognized their status in the dominant alliance, and approached Dawn, Whitney and Cochran, they could have taken control of the game from Coach, Sophie, Albert and Brandon with a 5-4 vote followed by a 5-3 vote.

But just replace Rick and Edna with Sophie and Albert (and vise versa) and I think there is still a chance.
Perhaps the initial status-reflex is not because they are at the bottom of the alliance but moreso (much like Jim felt with Ozyy) feel that Coach should lose some of his baggage. i,e; Edna, Rick (and even to a point Dawn. Because he noticed her inclusion with Coach and Brandon.)
When they last tried to take control of the game they were relying on Rick and Rick did not help them.
However, Dawn and Whitney will be desperate to make deals And Cochran wants to be included in big plays. The time could be ripe to rid Coach of too many final options.
