Well, its no use to complain - all they need to do is to perform better. Its always like that - a strong athlet in a sport doesn't guarantee that there will be always strong follow up from that country. Also the German Biathlon men dominated the sport for a while - and then, when the top stars retired, it was over.
Thats how it goes. Look at Boris Becker and Steffi Graf and the German Tennis sport. It was almost as popular as Football at one point, similar to Biathlon.
So lets see if they can find someone with the talent of a Neuner or Dahlmeier. If not... well, people will find something new, I guess.
