No, that's not true. Just because she can jump 3Lz and 3F Ripon doesn't mean she can do 2A also. That's not true for anyone. Even in interview she said salchow, toe loop, Axel are her worst jumps. You can see this example with many skaters, who are amazing at some jumps, bad at others. they are completely different and require different technique. For example Nathan who would rather do all quads any day and have so many difficulties with 3A. Or Mao, who can do 3A but has a bad lutz. You should not attribute one jump to others. Even look at juniors; Kostornaia has beautiful jumps, can do 3A now, still has a flutz many times. Skaters have their best and worst jumps, it's different for all of them. With Alina's 2A, you can tell it is off axis most of the time, and not very high. You do not have to be an expert to see that she does not have any prospects for 3A, and that's fine, she can try other quads on the jumps she better on.
