The speed and power are phenomenal. They are putting a colossal amount of pressure through the edges on the skates on to ice whose conditions change slightly on each lap as it gets carved.
The margin between success and error that impacts another skater is minute. It isn't deliberate, just an aspect and nature of the sport. It is fast and furious and very physical. Such mistakes do however have to be penalised. Disqualification is a constant risk, as is being taken out by another competitor.
It is remarkably easy to criticise. I bet few of us could even stand and walk on the ice in shoes without falling over never mind skating a corner at 30 mph that we wouldn't do in our cars! These are people at the pinnacle of their sport.
Anyone working at this level is clearly dedicated and talented. However, the form of these Olympics events are slightly different to World Championships. The temperament to perform under different situations has to be considered. Maybe that was a contributory factor here, and, if so, what was all the support around the teams doing to manage that? Then add the pressure of media expectation and then add cr*p doled out by people who only watch and comment every 4 years. It is lonely out there at the sharp end of anything.
That said, any sporting body deciding to not take a current and in form world champion and world record holder to the olympics really has to be sure of its decision.
There is a big team involved in preparation for an event that lasts but a few seconds. Lots of parameters involved in the decision.
Future funding will take in to consideration all recent performances. That is a brutal reality of much sports funding. That funding is only available based upon success and the likelihood of future success.
And of course, hindsight is a perfect science. Easy to be wise after the event.
