Also I know there was a rule about not leaving both feet to hit the buzzer. It was put in because Federov did some crazy jump flip into the netting thing in 2016.
Should have been enforce in both US and Europe as you have put yourself out of bounds. However I believe that is the first time it has been enforced in the US.
Sigh still the same old treating the rules as subjective rather than objective. It really, really needs to become this instance happebs this is the result, not this might be the result.
