Very rare in this game have the final 2 been "the best". Most of the time one of the smarter people will bring with them someone they know they can beat, for the "sure thing".
The goal of Big Brother is, has and always will be to "work smart, not work hard". Dan knows what he's doing, but I do think he's making a few mistakes lately (telling Boogie about Frank, and not wanting to put Boogie up for nomination).
If you want to have a battle of the bests in competitions, go watch Survivor. When a team/person throws a comp in Survivor, the results are disastrous. Just look at what happened to the one team that decided to throw a comp to get rid of Russell. Yes, they got rid of Russell. But then what happened? The opposing team whooped them in almost every comp after that, and the post-merger was almost all one-sided.
