I think her jumps have been getting weaker for years.
Specifically, I've always thought her pick was too crossed behind her, close, and "outside" the circle (rather than on it) on her flip.
Her loop was her best (obviously we saw 3loop on the back end of combinations in the past), but now they don't have much trajectory.
One thing about her early time with Tarasova was that she did a good 3lutz for a while. Then it disappeared.
Finally, I think her free leg has gotten lower and "draggy"er, especially in the past two years. There's no reason why most of her jumps don't have enough height and time to have a very clean landing, yet she's almost always close to being too crossed on the landings. I think part of it is that she was so used to doing loops on back ends of combinations.
Although in general early this season it seems like the rest of her skating skills have fallen off, I do chalk it up to being early season. I think her flow, lightness, and extension were the best last year, it's just she had awful programs.
It's just fascinating to me that after her 2006-07 Chopin SP, which was the perfect program for her, she's really had almost all duds that weigh down her skating skills. I think she's been overworking her jumps, whereas they seemed like she just "did" them in the 2005-07 era.
