I agree for the most part, except that its Big Brother, not Survivor. An obvious two person alliance will always be a target. Competition-wise, they were very strong. Strategy-wise, they were morons. The entire "us against them" mentality made them the obvious target week in and week out. That's the difference between two-person teams like Chilltown in seasons 2 and 7. Chilltown survived because they fooled people in not breaking them up. Brendon and Rachel dared everyone to vote them out...which obviously failed as a strategy. They failed to keep people like Ragan and Britney in their back pocket.
