But that also implies a drop of level. How many young German players really have the level to play in 1st league these days? Even a player like Helena Dornheim spent most of the time on bench of a weak team, what's the point of having her on court only because she is German? Matches are important, but players have to work for achieving enough quality in training, and if they don't get there a local player quota won't solve any problems IMO.
With a local player rule the German talents would not only be "side players" as in most teams of the league. They must be trained, because some of them have to play. In Italy it works. Lina Alsmeier wouldn't be "Lina Alsmeier of today" if she could not have played for USC Münster in the age of 16. Lina Alsmeier and Pia Timmer both have played for Emlichheim in the age of 15. If I remeber correctly Pia was perhaps a little bit better but both were on nearly the same level. And today?
Yes, in the near future it would be a drop of level.
But German league needs a drop of level. Stuttgart and Schwerin are financially to far away from the other teams. Only nine teams are left in Bundesliga. Many of them have financial issues. Dresden uses their very good talent work these years to compete (good for Germany but how long will it work?), Potsdam will drop level in the near future? And the others?
Neuwied played with many German talents and they really got better. These talents were not the best in their age. These places in squad could have been used better. In the end Neuwied pays the price. Bye bye but many thanks to them!
Has Helena Dornheim trained with first league team of Stuttgart in the age of 16 or 17? I cannot say anything about here way.
