Myth:
Angulated dogs have bad hips
There is no correlation between 'back slope' as you call it (which is mostly due to how the dogs are posed) and Canine Hip Dysplasia (CHD) "NONE"... nor is there a correlation between angulation and CHD. If there was, then why do flat backed, non-angulated breeds have so much more CHD than do GSDs? German Shepherds are #30 on the list with less than 19% dysplastic dogs out of 63635 sets of x-rays submitted to OFA updated October 2000. They are preceded by breeds such as:

I think most would admit that Rottweilers, Golden Retrievers, and
Otterhounds aren't terribly over angulated.
