I think B&A have to be considered as a top medal contender. One of the things that is going to be key this Olympics as who skates the Tango Romantica well, and how that skating is scored. Like DelSchoes, B&A have skated the TR quite a few times in competitions, but not recently. OTOH, they have always done well with Latin dances (except for falling on the Argentine Tango at Worlds in 2008), and Linichuk surely knows how the TR is supposed to be done. I would be surprised if they are not very close to the top in the CD.
So not all of us here are totally dismissive of B&A. However, their FD costumes at Nationals were so bad that they did make the dance look Elvis in Las Vegas. Mishmash is a bit harsh. The Cup of China costumes worked much much better IMO. And I see that Ben was out of the plastic Elvis suit in the Ice Works Olympic sendoff show, so I hope thye are going back to that.
