I don't know that Evora/Ladwig are comfortably in that "top two" yet, even if they bested D/B at the Olympics. Remember how narrowly they beat Inoue/Baldwin last year at Nationals? We can never count Rena and John out as they are returning, but if anyone is going to play spoiler, I'd go for Yankowskas and Coughlin. They couldn't hold it together at Nationals and seem to have a history of crumbling, but they have this "it" factor about them in my opinion that most other American pairs teams in history have not had. I don't see any of the younger teams really making a huge mark just yet.
