Several factors contribute to why the neck blends smoothly into the shoulders. Factors that contribute to a good blend include shoulder layback, shoulder blade set on the ribcage, and proper arch of neck.

Grooming can contribute to the "appearance" of a good blend of neck and shoulders. More coat on or behind the withers or at the base of neck can cover up lumpiness, lack of smooth blend, and ewe necks. Be sure to check the length of the hair throughout the transition.
