I doubt seriously too many of Zukill's pups were as good as he was. If any.

That is like saying, were any of Art's or Tornado's or QueenofHearts' pups as good as they were? No.

When a dog is that good, they pretty much are a "stand alone" item.
Dogs of that quality only come around once or twice in a lifetime, if that, and seldom throw what they were.

They all may have produced good ... even absolutely excellent ... dogs.
But very few freaks can throw another freak like they are.

When breeding, all dogs tend to "revert back to the average" of the line ... which is why it is so important to watch your averages when you breed, as opposed to getting caught up with "individual excellence."

That said, with 12 wins in one litter, Zukill should have been on rock-solid ground as a producer, since few litters in history have that many wins amongst the litter also.
