I don't think silver is a sure bet either. After all, D/R skated very well at Skate Canada and beat S/M there (a result that would have still happened even if scoring were outside of Canada). I'm glad S/K brought the 3-3 back, because they needed something to bring to the table technically to stand out. It'll be a very interesting battle.
I also don't think Silver is a sure bet, though I don't think D/R are the main challengers. Why do you claim "a result that would have still happened even if scoring were outside of Canada?"... I personally think S/M were pretty underscored in Canada, and D/R were overscored.
Look at the trends... S/M got scores that were lower than they had been getting for worse programs...at Nebelhorn they got higher TES and PCS even though all four of their throws and SBS were botched, versus only the SBS jumps at Canada. The technical score they received was the lowest they had gotten in over a year, even though they had a couple of even messier skates in that time.
Meanwhile, D/R got the highest PCS scores they had even gotten outside of Worlds 2016, despite a pop in the short and a messy watered down (albeit clean) version of their 14-15 free skate.
The reason for this? To ensure victory for the Canadians. D/R and S/M essentially had the same PCS in the free...would that have happened outside of Canada? And how about D/R's high SP score with a pop? The very fact that you feel the need to justify D/R's victory shows that you do think it is fair to acknowledge that D/R were overscored.
D/R still have made some improvements, such as a nice short by John Kerr, and should be credited as being a medal possibility. But it's unfair to misrepresent the scores from a heavily biased competition.
