Agreed, I think I remember seeing him at a national and thinking he would not make select at his rear was " Overdone" or "Too much".
and he never made select but I am not sure...just a loose memory.

The reason I remembered him at all was he had decent breed type
... and also being not happy when seeing the rear in person.

No picture of this dog yet. I saw him personally several times. The dog was so loose/wobbly in the rear that, when gaiting and fully extended, he would drag the toes of his hind feet along the ground!
