And the judges simply could not have placed Cohen above Nagasu and not expected rumors of "skandal" to erupt. Just like with refs in soccer or basketball games, there is only so much you can do to fix a result...the athlete (or team) still at least has to perform convincingly. But saying that, I absolutely DON'T think this was a fixed event, as screwy as the judging may have been.
EDIT:: Speculation: If they wanted to attempt to fix Nats to favor Cohen, they could have easily done this: give Nagasu and Cohen some buffer room in the short, giving both huge scores (keeping Nagasu as the overall leader to avoid mass suspicion) while marking Flatt down several points (the latter's what happened at the Olys, right?). This would allow Cohen a little more room for error in the FS since Flatt would almost certainly skate a clean (or strong) FS. Although this would STILL require Cohen to at least show competence in the long, deliver a respectably strong performance, in order to give the judges latitude to inflate her scores and thus put her into the top 2. Not that it would have done her any favors in the long run anyway.
EDIT II: Damn, I can't believe I'm actually saying this junk. It REALLY is off-season isn't it
