By "respectable"....Griazev's PB is 129 and change for a free skate. At Worlds last year, he earned 121 and change. BUT, he repeated the 3A, 3T and 3F, which meant his 3F-2T combo, which was done well, earned a zero. Add that to his score, and he would have been just a hair off of his PB. That, to me, is a respectable skate.
And the 21st in the short program was the result of a fall on a quad attempt, which also happened in the QR. At least he was trying to push himself technically. Sure, it bit him in the butt. But his technical content last year was at least improved over the two world's appearances prior.
