Why Oleg Antonenko holding the flag at the opening ceremony in Vancouver olypmics?

It is from Belarus, plays hockey on ice. Why was elected to take the flag?

I can not say if the team of Belarus uses the same method as the British team, but Shelly Rudman (skeleton Bob's wife) is designated by the team (ie, a survey was made by the entire Great Britain team, and had the highest number of nominations), so carrying the flag.
