How the hell would Ertl make the team? Germany didn’t nominate anyone in giant slalom, because they have pretty strict standards. In order to make the team Ertl would have to be good enough to regularly make top 30, which is completely unrealistic.
Most nations have the same problem. USA has Shiffrin and Johnson, Norway has Lysdahl and Lie, Slovakia only has Vlhova, Canada has Gagnon, Slovenia has Stuhec and Hrovat, Sweden has Hector, Finland has no one, France has Worley. The only nations with any depth are Austria, Switzerland and Italy. I am not saying that Germany has great depth, but that it is unrealistic to expect Germany to have great depth and that Germany basically never had great depth, except for a short exception in (giant) slalom. Meanwhile the men’s speed team is easily the best it has ever been.
In General one of the biggest problems of Germany seems to be the transition from juniors to seniors. Juniors don’t have enough „patience“ and retire, which leads to many great juniors never amounting to anything at senior level. This isn’t really a sports problem, but more of a political problem. You would have to find a way so that young people can stick around longer while still building a career.
