I don't know each side has a pretty good argument.
As for Bode, I think it was pretty odd to switch to a brand new ski right before an event. I would assume they would stick to tried and true. I recall another member switching back to the old skiis after Bode's run. As for his other mishap, missing a gate is a relatively common occurance. I mean when cutting that close you could always catch an edge (again on the new skiis) and turn too sharp.
For the snowboarder, it was a silly mistake, but it can pretty much be assured she won't make that mistake again, and neither will the rest of the team.
Apolo was bad luck too, putting his hand down in a turn is common, a skate that happened to be there isn't. Once again, he won't make that mistake again.
