What can be said that won't attract anger, derision and calls of cheating? It's pretty clear what most people think of Diana and Gleb.
For what it's worth I quite enjoy them, are they the greatest dance couple in history? No. Are they completely talentless and an embarrassment? No.
Although here's a question...let's say Diana and Gleb are aware of being overscored, what exactly would you have them do? Refuse their scores? Not accept their medals? Give up skating? It sounds like they're detractors would love to see just that. But no team would ever do that, nor should they be expected to. You got a problem with their scores? Roast the judges, curse the Russian Figure Skating Fed, don't take it out on two hard working kids who are doing the best they can.
