Not all the German units in France then were crap. But most of the best were in the East...
There’s a stereotype that the German Soldiers that fought on the Western Front were all old men and children to denegrate our fine troops. The Russians certainly said they were. It’s true the majority of the Wehrmacht was on the eastern front but some of their best divisions (especially Waffen-SS and Fallshirmjaeger units) were on the Western Front.
